Daylight saving time

Both zones observe daylight saving time, but they transition on different dates.

Greenwich Mean Time: next transition on Sunday, October 25, 2026.

Chile Time: next transition on Sunday, September 6, 2026.

Greenwich Mean Time and Chile Time are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
