Can I set an alarm for Brahma muhurta on Android?

Yes: Risetime can ring at the start of Brahma muhurta, or another time on this page, recalculated every day from sunrise where you are, offline. Pick the convention, copy the link, and import it in Risetime.

What time is Brahma muhurta?

It is the pre-dawn period before sunrise, so it moves every day. Many calendars count it as the muhurta that starts two muhurtas (96 minutes) before sunrise and lasts one muhurta (48 minutes); sources differ on the exact minutes. Some calendars divide the night into 15 equal parts instead. Risetime can ring at the start of either.

Why does Brahma muhurta change every day?

Because it is counted from sunrise. The definition in minutes keeps its length and slides with the sunrise; the one that divides the night by 15 also changes length with the season, because the night does.

What is Abhijit muhurta?

The eighth of the fifteen muhurtas of the day, centred around midday: about 48 minutes at the equinox and shorter in winter.

When is Pradosh kala?

The early evening, starting at sunset. Sources usually give it as about six ghatikas (about 2 hours 24 minutes) after sunset; some count three. The day on which the observance falls depends on the tithi, which Risetime does not use.

Does Risetime show Rahu kalam or the tithi?

No. It follows no calendar and no day of the week: it rings at a moment of the solar day on the days you set it to ring.

Does Risetime need an internet connection?

No. It computes the position of the Sun on the phone and has no internet permission at all. Your location never leaves the phone.

Brahma muhurta, sandhya and Abhijit: solar Hindu times

Risetime is a clock app for Android: alarms at a fixed time or following the sun, and timers that repeat and chain. No ads ever and completely offline.

Risetime does not set your practice times: communities count them in different ways, and choosing between them is not its place. You pick the conventions your community follows, and Risetime rings at them. Unsure which to follow? Check with your temple's panchang. Risetime is a clock, not an authority.

Which Hindu times follow the Sun?

Several daily times in Hindu practice are counted from the Sun, not from a clock: the Brahma muhurta before dawn, the three sandhyas at dawn, midday and dusk, the Abhijit muhurta at midday and the Pradosh kala in the early evening. They move a little every day and a lot between seasons, so an alarm at a fixed hour stops matching them after a few weeks.

In Risetime, each of these moments is an anchor: a moment of the solar day that the app calculates again every day for your location. You then set your own alarms on the anchors you choose: at the anchor, or a number of minutes before or after it.

Risetime alarm list with six alarms: Brahma muhurta 05:26, Every day, 1 hr 36 min before Sunrise; Pratah sandhya 06:14, Every day, 48 min before Sunrise; Work 08:30, Monday–Friday; Abhijit muhurta 12:26, Every day, Day 7/15; Sayam sandhya 18:14, Every day, 24 min before Sunset; and Pradosh kala 18:38, Every day, Sunset. — A list of alarms anchored to the sun, set up for a daily practice.

A muhurta is a fifteenth of the day, or of the night. A ghatika is a measure of about 24 minutes. Some sources give the length of a muhurta and of a ghatika as a fraction of the day, others as a fixed number of minutes.

Why do panchangs give different times?

Because they define the same moment in different ways:

Brahma muhurta: many calendars and Vaishnava sources count it as the muhurta that starts two muhurtas (96 minutes) before sunrise and lasts one muhurta (48 minutes); sources differ on the exact minutes. Some calendars divide the night into 15 equal parts and take the 14th, whose length follows the season. The two agree only when the night lasts twelve hours.
Sandhya: sources count in ghatikas around sunrise, noon and sunset. A ghatika is one sixtieth of a day (24 minutes); some calendars divide the actual day or night instead, so it varies.
Sunrise itself: calendars differ. Drik Panchang uses the upper edge of the Sun with refraction by default; some traditions take the middle of the disc, a few minutes later. There is no consensus.
Region and lineage: calendars differ by region and by sampradaya.

None of these is “the right one”. Your temple’s panchang (almanac) follows one of them; Risetime can follow the ones listed below.

How do I set an alarm for one of these times?

Sunrise, Noon and Sunset are ready to use, with an offset such as 48 minutes before sunrise. A muhurta counted as a fraction of the night or of the day is an anchor of the fraction kind. How anchors and offsets work — or let this page create them for you, further down.

The anchors, one by one

Each anchor is described below. Tick the ones you want to bring into Risetime: ticking opens its settings, and only ticked ones go into your links at the end.

These conventions come from public sources and I may have missed one, or got one wrong. If so, please write to me: I will fix it.

What an anchor can and cannot do

An anchor gives the time computed for your location. That time changes every day with the Sun.
One link describes one anchor. It is a rule, not a table of times: Risetime computes a new time each day.
It follows no calendar: it rings on the days you set it to ring.
Fixed offsets are in whole minutes.

Risetime is free for up to three alarms and three timers – forever. Need more? Use those three first, and see if it’s worth your support: supporters get unlimited alarms and timers, yearly or once. If not, I’ll be happy to read your message.
