Which cities match EST throughout 2026?
Lima, Peru; Bogota, Colombia; Quito, Ecuador; Kingston, Jamaica keep the same UTC−05:00 offset as fixed EST throughout 2026 under the published rules. Matching an offset does not mean every place uses the abbreviation EST.

The difference stays constant throughout 2026: EST is 14h behind compared with JST.
Does this conversion change the calendar date?
09:00 in JST on 2026-11-04 is 19:00 in EST on 2026-11-03. Use the destination date when adding the meeting to a calendar.
