Best times to propose
- 1. 3pm in Denver · 9am in Sydney — Right at the edge of someone's day
- 2. 4pm in Denver · 10am in Sydney — Comfortable mid-day slot on both sides
- 3. 5pm in Denver · 11am in Sydney — Right at the edge of someone's day
Avoid 9am Denver time and 10am Denver time — inside working hours locally but outside them for the other city.

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 — Melbourne Cup — Sydney is off, Denver is working.
- Wednesday, November 11, 2026 — Veterans Day — Denver is off, Sydney is working.
- Thursday, November 26, 2026 — Thanksgiving Day — Denver is off, Sydney is working.
- Friday, December 25, 2026 — Christmas Day and Christmas Day; both cities are off.
- Monday, December 28, 2026 — St. Stephen's Day — Sydney is off, Denver is working.
With 3 shared working hours, Denver and Sydney 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.
