Rahu Kalaya (Rahu Kalam) is a period in Hindu astrological tradition that some people consider when planning important activities. It is not a measure of physical risk or a scientific prediction.
Daylight length changes during the year, and solar times differ by longitude and latitude. This calculation assumes a level, unobstructed horizon, standard atmospheric refraction and the sun's apparent upper edge. Hills, weather, elevation and local almanac conventions can produce different times.
This is an informational astronomical calculation of a traditional time period, not a certified religious almanac or an official government timetable. Practices and preferred conventions may vary.
The time from local sunrise to sunset is split into eight equal parts. The weekday selects one part: Sunday 8, Monday 2, Tuesday 7, Wednesday 5, Thursday 6, Friday 4, Saturday 3. Sunrise and sunset are calculated for each selected date and city.
Times are approximate astronomical calculations, rounded to the nearest minute; they are not almanac-certified.
No. It is one eighth of the daylight interval, so its length changes with the season and location.
Printed almanacs may use a standard city, rounded sunrise times, or a different horizon or almanac convention. Compare the assumptions before relying on an exact minute.
No. All dates and displayed times explicitly use Asia/Colombo (Sri Lanka time), even when you travel.
No. Choose a listed city. No GPS permission or external astronomy service is used.
Select a Sri Lankan city and tap Today or Tomorrow to see the relevant period. The seven-day schedule also lets you open any listed date. Every result uses that day's sunrise and sunset in Sri Lanka time.
Yes. Select a date or use the seven-day schedule. Each weekday uses its traditional one-eighth segment of the sunrise-to-sunset interval; the calculator computes real start and end times for the city rather than assuming a fixed 90-minute slot.
