How it works (quick)

The tool interprets your input as a “wall clock” time in the source timezone, finds the corresponding instant (UTC), then formats that instant in the target timezone.

If your input falls into a DST gap or overlap, there may be no exact instant (or there may be two). The tool will show a note when that happens.

Common use cases

Meeting invites: convert between PST/EST/UTC and international timezones.
Logs/alerts: interpret timestamps from servers running in UTC.
Scheduling: verify time changes around daylight savings transitions.

Tips for accuracy

Prefer IANA names like America/New_York over abbreviations like “EST”.
When possible, store times as UTC + timezone, not as plain strings.
Be extra careful on DST change days.
