About this tool
Why time zone maths is tricky
Time differences change during the year because many countries use daylight saving time and switch on different dates. Pakistan, the UAE and Saudi Arabia do not use daylight saving, but the UK, Europe and most of North America do, so the gap between Karachi and London is five hours in winter and four in summer.
This converter uses your browser's built-in time zone database, the same IANA data used by phones and computers, so it applies the right offset for the exact date you choose rather than a fixed number of hours.
