Convertisseur de fuseau horaire — Convertir entre fuseaux horaires (heure d’été gérée, privé)

À propos de ce convertisseur de fuseau horaire

Coordinating across time zones is hard, especially when daylight saving time shifts dates and hours. This Time Zone Converter makes it easy to translate a date and time from one location to another so you can plan meetings, travel, or deadlines with confidence. It gives you clear, instant results without requiring any downloads or complicated settings.

The converter uses the IANA time zone database built into your browser, which means it respects official time zone rules and daylight saving time transitions automatically. You choose a base time zone, enter the date and time you care about, and the tool shows the equivalent time in one or two other zones. This is more reliable than doing manual offsets, because time zone rules change over time and can differ by region.

How to use it step by step

1. Select a base time zone from the list.
2. Enter a date and time, or click the Maintenant button to use the current moment.
3. Pick one or two target time zones to compare.
4. Toggle Format 12 h or 24-hour format depending on your preference.
5. Use Copier le lien to share the conversion with someone else.

Real-world use cases include scheduling remote meetings, coordinating international project deadlines, planning flights or live events, and converting webinar times for different audiences. If you work with global teams, a quick time zone conversion helps prevent missed calls or confusing time mix-ups. Students and travelers also use tools like this to compare local time against home time.

Everything runs locally in your browser for privacy. Some wall times do not exist during the DST “spring forward” change, so the converter nudges to the nearest valid minute. During the “fall back” transition, certain times repeat; the tool chooses the closest valid match based on the time zone rules.
