Choose a month within your solar-return year
This tool uses a month index from 1 to 12 within a selected annual return year. Month 1 begins at the annual solar return. The index is not the same as January, February or another civil calendar month.
Separate the natal and return locations
The birth record identifies the natal moment. The selected return city supplies the coordinates and time zone used for the return chart. Choosing another return location does not overwrite the natal birthplace.
Read the actual calculated interval
The report displays the return reference details and chart fields supplied by MahaGuru. Use the returned interval instead of assuming a calendar-month boundary. When signed in, the year, month index, location, profile and report are saved together.
How to use this calculator
- Check the prefilled birth details or select your own saved family profile.
- Enter a known birth time and select the correct birthplace.
- Generate the report. When signed in, your profile and the result save to your account automatically.
Frequently asked questions
Does month 1 mean January?
No. Month 1 is the first supported monthly segment of the selected solar-return year.
Can the return city differ from the birthplace?
Yes. Select a separate return city. The original birthplace remains part of the natal profile.
Will reopening restore the year and month I selected?
Yes. A successful signed-in report retains the return year, month index and location and restores those settings when reopened.
