Study the complete solar window
Choose a supported festival, year and city to inspect the native solar-window candidates. The selected source profile and month school remain part of the report.
Retain the availability context
Polar or otherwise unavailable anchors are not replaced with guessed dates. Read overlap values, candidate status and limitations before using the study as a reference.
Keep a reproducible reference
A confirmed signed-in save retains the selected settings and returned report in your account. Reopen it from saved reports to review the same inputs and method; changing the form later does not rewrite an existing report.
How to use this calculator
- Complete the inputs shown for this specific method. Use a saved family profile where relevant; a birth time or city is requested only when needed.
- Review the declared calculation convention and generate the report. Method differences and unavailable results remain visible.
- When signed in, wait for the cloud-save confirmation. Reopen saved reports from your account history to recover their settings.
Frequently asked questions
What happens when a required solar anchor is unavailable?
The report preserves the unresolved or unavailable state instead of manufacturing a complete festival decision.
Does this page cover every festival tradition?
It covers only the listed native source-rule variants. The report retains that scope and does not claim all regional practices.
Will this report be saved automatically?
When you are signed in, a successful calculation is saved to your account. Wait for the cloud-save confirmation before leaving the page; guest results are not account records.
