Timezone Converter

Convert a date/time between timezones (DST-aware). Pick a source timezone and target timezone, then copy the result. Local only.

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.

How it works

The converter treats your input as wall-clock time in the source zone, resolves the exact instant in UTC, then formats that instant in the target zone with DST rules applied.

Ambiguous or skipped times during DST snap to the nearest valid instant and surface a warning.
Results follow your browser time zone data; sync your clock for accurate output.

Quick examples

Meeting time

2026-02-14 09:30:00 America/New_York

2026-02-14 14:30:00 UTC

DST overlap

2026-11-01 01:30:00 America/Chicago

Warns if the time repeats

Prefer IANA names over abbreviations; offsets like -05:00 work but skip daylight rules.

Mini FAQ

Can I convert from offsets?

Yes. Use an offset as the source, but DST shifts will not be inferred.

Why is there a DST warning?

Some local times occur twice or not at all; the tool picks the nearest instant and tells you.
