Frequently Asked Questions
Does this account for daylight saving time?▾
No. Each zone uses a single fixed UTC offset, so conversions are stable and predictable. For dates around DST transitions the result may differ by an hour from reality.
Why does the date sometimes change after conversion?▾
When a zone is far ahead of or behind UTC, a mid-day time can cross midnight. The calculator shows the correct local date for every zone in the table.
