Daylight saving time: the next clock changes
- San Francisco: Sun, 1 Nov 2026: at 2:00 AM clocks go back to 1:00 AM (PDT → PST, UTC−8); Sun, 14 Mar 2027: at 2:00 AM clocks go forward to 3:00 AM (PST → PDT, UTC−7)

Good to know
- The two standard slots are 8:00–9:00 PM in California (9:30 AM next morning in Bengaluru in winter, 8:30 AM in summer) and 7:30 AM in California (9:00 PM in Bengaluru in summer).
- Rotate them. A team that always takes the late slot burns out.
- Write down handovers at the end of each day: the overlap is too short to explain things live.
