About this category
Time is one of the easier things to get wrong: seconds vs. milliseconds, UTC vs. local, naive vs. timezone-aware, leap years, business days, daylight-saving transitions. A small mistake in a timestamp shows up later as an off-by-one in a report or a customer complaining that an event fired at the wrong moment.
These tools give you a quick, consistent way to convert, parse, and reason about points and intervals in time — in your browser, with explicit handling for unit, timezone, and locale.
What you can do here
-
Timestamps in both units
Convert between seconds and milliseconds, parse ISO-8601 and RFC strings, and render local plus UTC outputs side-by-side.
-
Timezone-aware conversion
Translate a moment across IANA timezones with DST handling and a comparison view for scheduling across regions.
-
Date arithmetic and differences
Add or subtract days, weeks, months, or business days, and compute the difference between two dates with hour, day, and week breakdowns.
-
World clocks for distributed teams
Pin a row of city clocks for the cities and offices you collaborate with, so handoff windows are obvious at a glance.
