See two time zones side by side, live — free, no sign-up, nothing leaves your browser.
Both clocks update live and account for daylight saving time automatically. The shareable link keeps both places pre-filled and always shows the current time when opened, so it's better for bookmarking than a screenshot.
Time zones look like they should divide neatly into 24 one-hour bands around the globe, but in practice several countries use offsets that don't fit that pattern at all. India runs on UTC+5:30, a half-hour offset chosen as a compromise across the country's wide east-west span. Nepal goes further with UTC+5:45 — a 15-minute difference from neighboring India's time. A handful of other places, including parts of Australia and some Pacific islands, use similar half-hour or quarter-hour offsets rather than a clean whole number. This is exactly the kind of detail that trips up naive time zone math (just adding or subtracting whole hours), and part of why this tool relies on your browser's own built-in time zone data rather than a simplified lookup table.
Yes, automatically — the offset shown is always the current one for each place, including during DST transitions.
Places are drawn from your browser's own list of time zones, named after a representative city in each zone (e.g. "America/New_York" covers the whole US Eastern time zone, not just New York itself).
This tool is built around comparing two places side by side — for tracking several time zones at once, you'd want to check each pair individually.
No. Everything is calculated locally using your browser's own time zone data — nothing you select is sent to a server.
