Best times to propose

1. 5pm in San Francisco · 9am in Shanghai — Right at the edge of someone's day

Avoid 12am San Francisco time and 1am San Francisco time — only the other city is at work.

When the gap changes in the next twelve months

Sunday, March 14, 2027 — Shanghai goes from 16 hours ahead of to 15 hours ahead of San Francisco.

Recurring meetings set as a fixed clock time in one city will move by an hour for the other on that date.

Public holidays to avoid

Dates where one side is off work while the other is not are the most common cause of no-shows on this route.

Wednesday, November 11, 2026 — Veterans Day — San Francisco is off, Shanghai is working.
Thursday, November 26, 2026 — Thanksgiving Day — San Francisco is off, Shanghai is working.
Friday, December 25, 2026 — Christmas Day — San Francisco is off, Shanghai is working.

With 1 shared working hours, San Francisco and Shanghai can run standing meetings without anyone giving up an evening — as long as the slot sits inside that window on both sides of the next clock change.

Sending a booking link avoids the arithmetic entirely: each side picks a time in their own zone and both calendars get the correct local time, including after a daylight-saving change. See how LemCall handles cross-timezone bookings.
