About the panchang in Cupertino
Cupertino's clocks change twice a year: PDT (UTC−07:00) from Mar 9 until Nov 2 2025, and PST (UTC−08:00) the rest of the year. Every time on this page is local clock time with the change already applied; on the switch-over days, all timings jump by an hour.
Sunrise in Cupertino moves from 5:48 AM (Jun 7) to 7:34 AM (Nov 1), and daylight lasts from 9 h 32 min to 14 h 41 min. Rahu Kalam, Yamaganda and Gulika are each one-eighth of the daytime, so in Cupertino they last about 72 minutes in the shortest days and 110 minutes in the longest: never a fixed 90 minutes, and never fixed clock times.
Dates can differ from India too. Tithis are counted from local sunrise, so in 2025, 13 of the 25 Ekadashis in Cupertino fall on a different day than in India. That is why a panchang made for India can give the wrong fasting day here.
All calculations use Drik Ganita: Cupertino's own sunrise and sunset (NOAA solar formulas) and the true positions of the Sun and Moon (Astronomy Engine, validated against NASA JPL), with Lahiri ayanamsa.
