The best time for a call

A 9-to-5 day in San Francisco and one in Bangalore don’t overlap at all, so somebody has to stretch. The fairest one-hour slot is usually 6:30 PM in San Francisco, which is 7:00 AM the next day in Bangalore. It asks San Francisco to stay about two and a half hours late and Bangalore to start about two hours early.

This is one of the busiest routes in tech and one of the hardest to schedule: 12½ hours apart in the US summer and 13½ in winter, with no daylight saving time in India to soften it. Bangalore, officially Bengaluru, is on India Standard Time like the rest of the country.

The usual pattern is a short sync in the San Francisco evening, which is Bangalore’s morning, or first thing in San Francisco, which is Bangalore’s evening. Because of the half-hour offset, an on-the-hour time in one city is a half-hour time in the other, so double-check any invite that was typed in by hand.
