Methodology

A Pancha Pakshi day runs from sunrise to the next sunrise, not from midnight to midnight. Sunrise, sunset, and the following sunrise are calculated precisely for your exact latitude, longitude, and timezone.

Your birth bird is derived from your birth Nakshatra and Paksha (waxing or waning moon), following the traditional five-bird mapping, or can be selected directly if your birth details aren't known.

Each day is divided into 10 major periods (5 during the day, 5 at night) and 50 detailed sub-periods (5 within each major period), sourced from the pinned calculation engine's reference data — never invented or manually entered.

All calculations use IANA timezones and account for daylight-saving transitions on the specific date requested.

This is a traditional system provided for cultural and informational purposes; see the disclaimer for its limits.
