HourSwift is a time zone converter: it converts a time across zones, compares several at once and finds a meeting slot that suits everyone, following daylight-saving changes as they happen. In practice, it resolves each zone to its offset from UTC for the date in question using the IANA time-zone database, so a city that has moved to summer time shifts in the answer automatically instead of by a fixed number of hours. This page should be read with that tool in mind, because the limits described apply to what it computes.

Practically, all the calculation needs is the times and zones you pick. Typical reasons people open HourSwift include checking whether an overseas office is open, and in every case the work happens on the visitor's own device rather than ours.

General information only

hourswift.com is an informational site. What HourSwift produces are estimates of a calculation, not measured facts and not professional guidance.

Everyday tools

HourSwift gives a quick, general answer. For anything with a consequence — a measurement that gets built from, a number that gets filed — verify the result independently.

No warranty

The assumption that matters most for HourSwift is that your input matches the model. It resolves each zone to its offset from UTC for the date in question using the IANA time-zone database, so a city that has moved to summer time shifts in the answer automatically instead of by a fixed number of hours. When it does not — or when rounding, unit handling or browser behavior intervenes — no warranty attaches to the Site, careful as we are with the method.
