Convertidor de zonas horarias

Cómo funciona

1. The source wall time (date, time, zone) is resolved to the exact instant it denotes; the daylight-saving offset in effect on that date is part of the resolution, not an afterthought.
2. That single instant is then rendered as wall time in every target zone you add. Each row resolves its own offset for the same instant, so times near a clock change stay correct.
3. When a target’s calendar date differs from the source date, the row marks it (previous day / next day), which prevents scheduling errors across midnight.

Información útil

• Pick IANA zone names (like America/New_York), not fixed offsets: identifiers carry each region’s full rulebook, so conversions stay accurate across DST changes.
• Source times that do not exist (spring-forward gaps) or occur twice (fall-back overlaps) are detected and labeled; the converter states which occurrence it used.
• Up to 12 target zones can be compared at once, and rows can be removed individually.
