Our Time Calculator is highly accurate and accounts for leap years, daylight saving time changes, and varying month lengths. Calculations are precise down to the second.
Currently, the calculator uses your local time zone for all calculations. We recommend converting both times to UTC before entering them for time zone-independent calculations.
The calculator uses the JavaScript Date object which automatically adjusts for daylight saving time based on your system's time zone settings.
Currently, the calculator works with calendar days. For business day calculations, you would need to account for weekends and holidays separately.
