Select any two time zones to see their current local times side by side and the exact hours and minutes between them. The offset updates automatically for daylight saving time changes.
Most time zones observe daylight saving time (DST), shifting clocks by 1 hour for part of the year. Since different regions switch on different dates, the offset between two zones can temporarily change.
Some countries use half-hour or quarter-hour offsets — for example, India (UTC+5:30) and Nepal (UTC+5:45). This is a historical and political choice rather than a technical one.
