How to report a date you believe is wrong
These are the most valuable messages we receive. To let us act on one quickly, include four things:
- 1
The exact request
The full URL including date, location and any pack parameter.
- 2
What we returned
Paste the response, or at minimum the festival key and confidence score.
- 3
What you expected
The date you believe is correct.
- 4
Your source
The panchang, almanac or authority you are comparing against. This matters — where authorities genuinely differ, the right answer may be a new rule pack rather than a correction.
