Find exactly how long it is from one date and time to another — in days, hours and minutes, in months and days, and as total hours or minutes.
Enter the start and end, then press Calculate duration.
Days, hours and minutes counts every full day of 24 hours. Months and days counts calendar months first, which is how people usually say an age or a period ("2 months and 14 days"). The totals are the same span in a single unit.
Enter both dates and times; the result gives the total hours (and minutes, days and weeks) as well as days, hours and minutes.
8 hours 30 minutes, or 8.5 hours.
Yes. It uses your device's time zone, so on the night the clocks change the duration is an hour shorter or longer, as it really is.
Times are in your device's time zone, so a daylight-saving change between the two dates is included.
