How the time zone calculator works
Conversions use the IANA time zone database built into your browser, the same data your phone uses, so daylight saving time rules and historical changes are applied for the exact date you pick.
The difference between two zones can change during the year, because not every country switches to daylight saving time, and those that do switch on different dates. That's why the date matters, not just the time.
