Convert a date and time from one time zone to another, with daylight saving time handled automatically.
Rather than using a fixed UTC offset per region, this calculator looks up each location's real time zone rules for the exact date you enter — so a conversion in July (daylight saving time) and one in January (standard time) for the same two cities correctly come out an hour apart where that applies.
The "Difference from origin" line shows how many hours ahead or behind the destination is compared to your starting time zone, for that specific date. This gap can change across the year in places that observe daylight saving.
This tool doesn't rely on your device's time zone at all — you pick both the origin and destination explicitly, so the result is the same no matter where you're browsing from.
It covers major regions and population centers rather than every offset variant. For a precise city not listed, pick the nearest major city that shares its time zone rules.
