Frequently asked questions
How is the time difference between two cities calculated?
The difference is the gap between the two time zones' UTC offsets at a given moment. We compute it from the official IANA time-zone database, so daylight saving time is handled automatically.
Why does the difference change during the year?
Because not every country observes DST, and those that do switch on different dates. Bulgaria and the UK switch together (the difference stays 2 hours), but Bulgaria and Dubai do not (1 hour in summer, 2 in winter).
Is the difference the same in both directions?
The magnitude is the same but the sign flips: if Sofia is 2 hours ahead of London, London is 2 hours behind Sofia.
Which cities are included?
48 world cities — the main Bulgarian cities, every major European capital and the world's principal hubs. For other cities use the timezone converter.
