Note on DST transitions: The offsets shown above reflect the current live offset, which changes twice a year due to Daylight Saving Time. The US, EU, and other regions change their clocks on different dates, which means the difference between Boise and a European city can vary by 1 hour for a short period in spring and autumn. Always verify the exact time difference around DST transition dates for critical scheduling.
