Frequently asked questions
It resolves each city’s offset from the IANA time zone database for the exact date you enter, so a date in summer uses the daylight-saving offset and a winter date uses the standard one — automatically.
Pick the time with the 12-hour hour/minute selectors and the AM/PM toggle, then choose the date. Results are shown in 12-hour format too, with a 24-hour toggle available.
When the offset gap is large enough, the converted time can land on a different calendar day. The label flags when the result rolls into the previous or next day.
No. India uses a single zone, IST (UTC+5:30), with no daylight saving, so conversions involving India shift only by the other city’s seasonal changes.
The same two cities, a different gap depending on the season
Convert 15 June 2026 in London to IST (India), and the calculator first resolves London's offset for that specific date. Mid-June sits within British Summer Time, so London runs at UTC+1, while IST holds a constant UTC+5:30 year-round — a 4-hour-30-minute gap. Convert the identical clock time in mid-January instead, when London reverts to UTC+0 for winter, and the gap widens to a full 5 hours 30 minutes. Same two cities, same time of day entered, a genuinely different answer — purely because of the season.
Why the date you pick matters as much as the time
The key to getting this right is daylight saving. Rather than storing a fixed offset per city — which would be wrong for roughly half the year in any DST-observing location — the converter looks up each zone's offset from the IANA time zone database for the specific date you choose, not just the time. So converting a July time correctly uses summer offsets, a January time uses winter offsets, and the result stays accurate even across the actual switchover weekend, including the skipped hour in spring and the repeated hour in autumn that trip up naive fixed-offset calculations.
India is the simple reference point in any such conversion: IST is a constant UTC+5:30 with no daylight saving, so when converting to or from India, only the other city's seasonal change moves the gap. For a live multi-city dashboard rather than a single conversion, use the world clock; to find a meeting slot that suits several zones at once, try the meeting time planner.
