Quick answer: The strongest general results in Sidera’s 507-day calculation for ending a relationship include July 29, 2027 (5.0/5), April 24, 2027 (5.0/5), January 28, 2027 (5.0/5). They are ranked by favorability, quality, intensity, and then date—not chronologically. These are monthly day-level leaders at 12:00 UTC, not personal guarantees. Start with dates you can realistically use, then refine the exact local time and keep the real-world decision criteria ahead of the score.
Why these three passed:
- July 29, 2027 — 5.0/5: Uncapped total 5.95; quality 10.0, intensity 8.3; Waning Crescent; strongest modifier moon phase +0.40.
- April 24, 2027 — 5.0/5: Uncapped total 7.12; quality 10.0, intensity 6.5; Waning Gibbous; strongest modifier aspects +1.32.
- January 28, 2027 — 5.0/5: Uncapped total 5.50; quality 9.7, intensity 4.6; Waning Gibbous; strongest modifier moon phase +0.30.
For a nearer option, the first qualifying date in the partial 2026 range is August 28, 2026 (4.8/5); use it only if it also fits the practical and safety constraints below.
There is no painless breakup date, and waiting for a perfect Moon can become another way to postpone a decision you already understand. Timing is useful only after the safety, housing, financial, and communication realities are faced. The goal is not to make the other person approve of the ending; it is to communicate clearly and reduce preventable harm.
Sidera’s end-relationship model emphasizes Saturn, Pluto, and the Moon and prefers the waning part of the lunar cycle. It does not treat retrogrades or void-of-course Moon as automatic blocks, because closure and boundary-setting follow different rules from beginnings and commitments.
The Decision Behind the Date
Separate uncertainty about how to end the relationship from uncertainty about whether to end it. If the decision is not final, choose a relationship conversation instead. If it is final, prepare one clear statement, the immediate logistics, and the boundary you will keep afterward. In any situation involving coercion or violence, use a safety plan and professional support rather than a private electional meeting.
For a relationship decision, a strong election should make honesty easier, not make another person’s response predictable. Consent, safety, mutual capacity, and direct communication stay outside the score. Use the calendar after those conditions are real, and notice if the search for a better date is helping you prepare or helping you avoid the conversation.

General transit-only calculation, generated August 12, 2026 with Sidera engine baseline 382200b. Every calendar day was evaluated with the current Sidera end_relationship model at 12:00 UTC. The monthly result must score at least 4.5/5, match the activity's waning Moon preference, and pass every VOC or retrograde rule that activity actually enforces. Ties use quality, intensity, then the earliest date. No birth chart or location was used.
The 2026 portion begins on August 12, so it should not be read as a full-year calendar. Every month contains at least one date that clears the current publication filter. The table is rendered as normal HTML during the Hugo build, which means readers and search engines can see the date, score, Moon phase, reason, and provenance without opening the app or running JavaScript.

Worked score example
July 29, 2027: Displayed inputs: base 5.8 + Moon phase +0.40 + VOC +0.00 + retrogrades +0.00 + aspects -0.25 = 5.95 before the 1–5 cap, producing 5.0/5.
Uncapped total 5.95; quality 10.0, intensity 8.3; Waning Crescent; strongest modifier moon phase +0.40.
How the top dates differ
| Date | Score | Quality | Intensity | Practical distinction |
|---|---|---|---|---|
| 5.0/5 | 10.0 | 8.3 | Uncapped total 5.95; quality 10.0, intensity 8.3; Waning Crescent; strongest modifier moon phase +0.40. | |
| 5.0/5 | 10.0 | 6.5 | Uncapped total 7.12; quality 10.0, intensity 6.5; Waning Gibbous; strongest modifier aspects +1.32. | |
| 5.0/5 | 9.7 | 4.6 | Uncapped total 5.50; quality 9.7, intensity 4.6; Waning Gibbous; strongest modifier moon phase +0.30. |
Practical decision tree
- Keep only feasible dates: Remove dates that fail safety, consent, health, legal, financial, access, or scheduling constraints before comparing astrology.
- Apply the end_relationship score: Compare the engine's 507-day output at the shared 12:00 UTC reference time.
- Apply publication gates: Require at least 4.5/5, one of Full Moon, Last Quarter, Waning Crescent, Waning Gibbous, VOC=disclosed, and no avoided retrogrades (none).
- Break capped-score ties: Use quality, then intensity, then the earliest date; inspect the uncapped total and modifiers to understand practical differences.
- Refine the real start: Define the operative action and verify the exact local time and personalized chart only after the day-level shortlist is practical.
Score method
final = clamp(base + Moon phase + VOC + retrograde + relevant-aspect modifiers, 1, 5)
Quality 1–10 is mapped to a 1.5–5.0 base, then intensity amplifies or tempers that base using the current Sidera activity engine rules. Publish only dates at or above 4.5/5 that also pass the activity's phase, VOC, and avoided-retrograde gates; rank by score, quality, intensity, then earliest date.
General transit-only calculation, generated August 12, 2026 with Sidera engine baseline 382200b. Every calendar day was evaluated with the current Sidera end_relationship model at 12:00 UTC. The monthly result must score at least 4.5/5, match the activity's waning Moon preference, and pass every VOC or retrograde rule that activity actually enforces. Ties use quality, intensity, then the earliest date. No birth chart or location was used.
Use the 2027 table as a comparison layer rather than a promise. A month-level winner may be impossible for your schedule, location, budget, or other people. When that happens, compare the next feasible dates in the Sidera app instead of treating the published leader as the only acceptable choice.
What the Sidera Score Actually Measures
This calendar is generated from Sidera’s current end_relationship activity definition and Western tropical timing engine. The activity emphasizes Saturn, Pluto, Moon. Its Moon-phase preference is waning; void-of-course Moon is disclosed but not a hard publication gate; the activity definition asks the publication layer to avoid these retrogrades: none.
Every day from August 12, 2026 through December 31, 2027 was evaluated at the same reference time, 12:00 UTC. A monthly recommendation must reach at least 4.5/5, pass the phase gate, and pass any VOC or retrograde gate that this activity definition actually enforces. Qualified dates are ordered by favorability, then quality, then intensity, then the earliest date. The rejected examples matter because they show why a high raw score alone is not sufficient.
The result is general transit-only timing. No birth time, natal positions, local Ascendant, houses, or personal transits were used. Read the score as a reproducible shortlist generated from the product, not as “your lucky date.” For the larger framework, see what electional astrology is and how it is used.
How to Read Score, Quality, and Intensity
The 1–5 favorability score combines the day’s base quality and intensity with modifiers for the activity. Quality describes how harmonious or challenging the active aspect pattern is in Sidera’s engine. Intensity describes how active that pattern is. A high-intensity day can amplify support, but it can also make a difficult pattern feel louder.
That is why two 5.0/5 dates can still feel different. One may be quiet with clean supportive factors; another may be busy, visible, or emotionally demanding. Read the “Why it passed” cell and choose the pattern that fits the action. Also check the void-of-course Moon calendar when the exact local hour matters.
Four Practical Filters to Apply First
- Physical and digital safety: Choose a public, remote, or supported format when a private meeting could create danger, intimidation, or surveillance.
- Immediate logistics: Know where each person will sleep, how keys and belongings will be handled, and what must happen in the next twenty-four hours.
- Financial exposure: Secure essential documents, accounts, transportation, and professional advice before announcing a high-conflict separation.
- Support after the talk: Arrange a friend, therapist, advocate, or safe place so neither person is left in avoidable crisis.
Astrology belongs after these filters, not before them. If the highest-ranked date fails a basic practical requirement, remove it and compare the next feasible option. The purpose of a non-commodity calendar is to improve a decision, not to make the decision rigid.
What Moment Actually Starts the Event?
The action begins when the ending is stated unambiguously. A vague request for space can prolong negotiation if you actually mean the relationship is over. For shared homes, finances, children, or legal obligations, the conversation is only one moment in a longer separation timeline; each practical step may need its own plan.
This distinction is a recurring gap in generic lucky-date lists. Searching for “the best day” is not enough until the initiating action is defined. A booking, preparation task, signature, conversation, public release, physical departure, and first use can each create different event charts. Use the action that carries the real commitment or consequence.
A Timeline That Makes the Date Useful
Before selecting a date
Decide whether this is a final ending, a trial separation, or a conversation about conditions for continuing.
One week out
Prepare safety, housing, money, transport, belongings, and any legal or caregiving questions.
Opening minute
Use direct language without a catalogue of every flaw or an invitation to debate your basic boundary.
First day after
Follow the communication and contact rules you stated; mixed messages prolong pain.
First month
Handle shared obligations in writing and seek qualified legal or clinical help where needed.
The timeline converts symbolic timing into observable preparation. If it exposes a missing dependency, solve that dependency before trying to refine the astrology. A high score is most useful when the surrounding system can carry the action.
What Current Search Results and Readers Miss
Three source-backed signals shaped this page:
- Reddit r/witchcraft, When is a good time to break up with someone?: People seeking breakup timing are often less confused about Moon phases than about how to make a painful boundary real without causing unnecessary harm.
- Reddit r/astrology, How do you select the best date to start something?: Readers discover that a generic lucky weekday is not enough: location, the Moon, and the chart of the actual start moment can change the choice.
- Reddit r/astrology, Is it bad to start anything new during Mercury Rx?: People often treat Mercury retrograde as an absolute prohibition, then need a practical way to handle a date they cannot move.
These signals were reviewed on August 12, 2026. They are qualitative evidence, not a representative survey and not proof that astrology changes outcomes.
The current search landscape has two recurring gaps. First, breakup timing results often use dramatic best/worst date lists without a safety, housing, money, or support protocol. Second, few pages distinguish a final ending from a repair conversation or explain why a release activity uses different Sidera gates from a wedding. Sidera’s contribution is the crawlable monthly dataset, the visible hold months and rejections, and a decision process that shows where astrology stops.
If Your Date Is Fixed
If the day is fixed, keep every consent and safety safeguard, refine the exact local-time window when useful, and prepare for the conditions the chart highlights. Do not use the score to pressure another person or interpret their response for them.
Fixed dates are normal. Electional astrology is often the art of choosing the least-friction option inside a narrow window, then compensating for what cannot be changed. You can also refine the first meaningful action within the day—provided that doing so does not create safety, legal, financial, or relational problems.
General Timing Versus Your Chart
The published calendar holds time constant so every candidate can be compared reproducibly. Personalization can reorder the list because a birth chart adds natal contacts, houses, angles, and individual sensitivities. Location also changes the exact local clock and chart angles. A date that ranks first in the general table can move down when those layers are added.
Use the general calendar to narrow a large range. Use the app or a qualified electional astrologer to compare exact local times for a major commitment. Never describe a general score as personalized, and never infer another person’s consent, health, financial capacity, or future behavior from it.
Common Mistakes
- Waiting for certainty without grief: A correct decision can still hurt. Pain after the ending does not automatically mean it was wrong.
- Choosing symbolism over safety: No lunar phase is worth an unsafe private confrontation.
- Turning the breakup into a prosecution: Specific reasons matter, but a final boundary does not require winning a historical argument.
- Continuing couple behavior afterward: Unclear contact, intimacy, and favors can undermine the boundary both people need to adapt.
One more mistake is treating a hold month as bad luck. A hold only says that no day in that month cleared this article’s 4.5/5 publication threshold and activity-specific gates at the fixed reference time. It does not say nothing valuable can happen, and it is not a reason to miss a necessary or time-sensitive opportunity.
Evidence and Methodology Notes
- Cafe Astrology’s breakup context offers broader astrological reflection on relationship endings.
- Cafe Astrology’s Moon timing guide explains the waxing, waning, and VOC terminology used here.
The product-derived evidence comes from Sidera’s local activity engine at baseline 382200b, verified against revision 3a07933 recorded in the dataset. The exporter stores all visible scores, factors, filters, timestamps, and provenance in blog/data/sidera/end-relationship-2026-2027.json. The source research is used for context and reader needs; it does not validate astrological causation.
There is no established scientific evidence that planetary positions cause the outcome of this action. Use this framework as a reflective planning practice. Real outcomes depend on preparation, behavior, other people, material conditions, and chance.
Frequently Asked Questions
Is a waning Moon best for a breakup?
Sidera’s end-relationship model prefers waning phases because the activity is about release. Safety and clear logistics outrank that symbolic preference.
Should I avoid Mercury retrograde?
This activity does not hard-block retrogrades. If important facts, leases, or agreements are involved, put them in writing and verify details.
Is text an acceptable way to break up?
It can be appropriate for safety, distance, a brief relationship, or repeated boundary violations. Choose the format that protects clarity and wellbeing.
What if we live together?
Treat the emotional conversation and the housing transition as separate workstreams. Prepare access, money, belongings, pets, and legal rights before the talk.
Can astrology tell me whether to leave?
No. Astrology may support reflection about timing, but it cannot determine consent, safety, compatibility, or the decision for you.
