The best meeting windows
In January, the best windows are 09:00–17:00 in Santiago, which is 05:00–13:00 in Denver. These are the hours inside both working days. It is a short window, so keep the meeting to 30 minutes and send the agenda in advance.
In July the best windows are 09:00–17:00 in Santiago (07:00–15:00 in Denver).
Daylight saving and the overlap
Santiago observes daylight saving: in 2026 the clocks go forward on 6 September 2026 and back on 4 April 2026, moving the offset from UTC−04:00 to UTC−03:00.
Denver observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−07:00 to UTC−06:00.
The overlap shifts on Sunday, 8 March 2026 and Sunday, 6 September 2026 and Sunday, 1 November 2026 in 2026, when the difference between the cities changes from 4 hours behind to 3 hours behind (and again on the later dates). A recurring meeting set in one city's local time will move by an hour on the other side on those dates. Set the calendar event in UTC to avoid it, or check the overlap again after each change. The DST pages — Santiago DST 2026 and Denver DST 2026 — give the exact dates.
Scheduling etiquette for Santiago and Denver
Scheduling inside the Americas is usually straightforward: the difference between Santiago and Denver is small, and the working days overlap for most of the day. The main thing to check is daylight saving — not every place in the Americas observes it, and the ones that do change on different dates (the United States and Canada in March and November, Chile in September and April, Mexico not at all since 2022).
A few rules apply to every pair. Avoid Monday mornings and Friday afternoons — they are the edges of the week in every zone, and a meeting there is the first to be skipped. Avoid the weeks when the clocks change — the overlap moves, and a standing meeting lands at the wrong time. Always send the time in UTC as well as in each participant's local time, so nobody has to do the conversion in their head. And if the meeting has to happen outside someone's working hours, rotate it: a team that always meets at 09:00 in Santiago is always meeting at 05:00 in Denver, and the Denver side will quietly disengage if that hour is always theirs to give up.

Making it work week to week
The overlap between Santiago and Denver is comfortable — 8 hours in January — so a recurring meeting is easy to keep. Pick a time in the middle of the overlap rather than at its edge: a meeting at the edge is the first to be missed when someone is running late, and it is the one that runs over into someone's evening. Put the UTC time in the invitation, keep the meeting to 30 minutes where you can, and send the agenda the day before so the meeting itself is for decisions, not for updates.
Whatever the overlap, the calendar mechanics are the same: set the event in UTC, not in local time, so it moves correctly when the clocks change; include the local time for each city in the invitation body; and re-check the overlap in March and October, when the difference moves. The meeting time finder finds the overlap for a whole team, and the time difference calculator works out the difference for any date.
