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.

Tuesday, November 3, 2026 — Culture Day — Tokyo is off, Dublin is working.
Monday, November 23, 2026 — Labour Thanksgiving Day — Tokyo is off, Dublin is working.
Friday, December 25, 2026 — Christmas Day — Dublin is off, Tokyo is working.
Saturday, December 26, 2026 — St. Stephen's Day — Dublin is off, Tokyo is working.

Dublin and Tokyo have no shared working hours, so a recurring live meeting always costs someone their morning or their evening. Rotating the burden, or moving the update to written form, is usually the better answer.

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.
