Work out unix timestamp to date instantly with clear inputs, formula shown and shareable results.
A timestamp identifies an instant, not a wall-clock reading, so a time zone offset must be applied to display it locally. Timestamp 1767225600 is 2026-01-01 00:00 UTC, which is 05:30 on the same day in India at UTC+5:30 - so the local date can differ from the UTC date near midnight.
Local display
local instant = timestamp + offset x 3600 seconds
Day of year
days elapsed since 1 January of that year, plus one
Because offsets can push the local time past midnight in either direction, so the same instant can be two different calendar dates.
No. The timestamp is absolute; only its human-readable rendering changes with offset.
