Tomorrow’s sunrise in San Francisco is 6:55 AM, so Brahma Muhurta, the fourteenth of the night’s fifteen muhurtas, runs 5:21 AM – 6:08 AM, ending 47 minutes before the sun. This morning’s window, before today’s sunrise at 6:54 AM, was 5:21 AM – 6:08 AM.

Tonight in San Francisco is 11 hr 43 min long, from sunset at 7:13 PM to sunrise, so each night muhurta is 47 min. That is why the window is not a fixed "4 to 5:30": it is tied to San Francisco’s own dawn and moves with the season, earlier in summer and later in winter.

If you are setting an alarm here, 5:21 AM is the start of the window and 6:08 AM the end. Practice begun anywhere inside it counts; most people aim to be awake for the start.

Brahma Muhurta in San Francisco: questions

What time is Brahma Muhurta tomorrow in San Francisco?▼

5:21 AM – 6:08 AM, ahead of sunrise at 6:55 AM in San Francisco. It is computed from the city’s own sunrise, not a fixed clock time.

What time should I wake up for Brahma Muhurta in San Francisco?▼

To be up for the whole window, by 5:21 AM. The window ends at 6:08 AM, 47 minutes before San Francisco’s sunrise, so there is a short margin after it before the day begins.

Is Brahma Muhurta always at 4 AM in San Francisco?▼

No. It is the 14th muhurta of the night, and tonight’s muhurtas in San Francisco are 47 min each, so the window lands at 5:21 AM – 6:08 AM, earlier in midsummer and later in midwinter. "4 AM" is a rough rule of thumb for a twelve-hour night, not the timing itself.
