Best times to propose

1. 4pm in Hong Kong · 9am in London — Right at the edge of someone's day
2. 5pm in Hong Kong · 10am in London — Right at the edge of someone's day

Avoid 12am Hong Kong time and 9am Hong Kong time — only the other city is at work.

When the gap changes in the next twelve months

Sunday, October 25, 2026 — London goes from 7 hours behind to 8 hours behind Hong Kong.
Sunday, March 28, 2027 — London goes from 8 hours behind to 7 hours behind Hong Kong.

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

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.

Saturday, September 26, 2026 — Day following the Mid-Autumn Festival — Hong Kong is off, London is working.
Thursday, October 1, 2026 — National Day — Hong Kong is off, London is working.
Monday, October 19, 2026 — Chung Yeung Festival — Hong Kong is off, London is working.
Monday, November 30, 2026 — Saint Andrew's Day — London is off, Hong Kong is working.
Friday, December 25, 2026 — Christmas Day and Christmas Day; both cities are off.
Saturday, December 26, 2026 — Boxing Day — Hong Kong is off, London is working.
Monday, December 28, 2026 — St. Stephen's Day — London is off, Hong Kong is working.

With 2 shared working hours, Hong Kong and London 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.
