Why should you trust our online time converter?

We use the IANA time zone database for calculating our time zone conversions. IANA is a well-known reputable source that coordinates and manages world timezone data.

Most other sites use a static offset to convert between time zones. However, this method is prone to errors due to geopolitical events and daylight savings time changes. That is why we regularly update our time zone database so that you can be confident our time information is 100% accurate.
