Why Rahu Kaal Times Differ by City

All supported pages display Indian Standard Time, but sunrise and sunset are local solar events. India spans a wide range of longitude and latitude, so the Sun does not rise and set at the same IST clock time everywhere.

Rahu Kaal uses a fraction of each city’s daylight. When sunrise or sunset shifts, the daylight intervals shift too.

Longitude strongly affects where solar noon and sunrise fall on the clock. Locations farther east generally reach solar events earlier by IST than locations farther west on comparable dates. Latitude and season affect day length, which changes the duration of each one-eighth segment.

These effects combine, so it is better to calculate the selected city and date than to copy a time from another place.

Even nearby cities use different reference coordinates. On some dates, two results can round to the same minute; on other dates they can differ by a few minutes. A rounded match does not mean the underlying sunrise and sunset timestamps are identical.

Each city page lists nearby supported alternatives so users can choose the page that best matches the intended location.

Use the nearest supported city as a practical reference, but treat the result as an approximation for your location. Do not claim that a supported city’s timetable is exact for a different place. If exact ceremonial timing is important, check a local Panchang or practitioner using the intended location.
