The answer

From 12:00 PM to 8:00 PM is 8 hours, which is 480 minutes or 8 in decimal hours. Both times fall on the same day, so no midnight is crossed.

Decimal hours for timesheets

Payroll systems usually want decimal hours: 7 hours 30 minutes is 7.5, and 8 hours 15 minutes is 8.25. The table above shows the time worked with a break of 15, 30, 45 or 60 minutes taken off. Over five identical days the total is 40 hours before breaks, which is a quick check for a weekly total.

How the span is counted

The calculation converts each time to minutes after midnight and subtracts. When the end is earlier than the start it adds 24 hours, which is how night shifts and overnight travel are measured. Identical start and end times are not accepted, because the answer could be zero or a full day. Clock changes for daylight saving are not included, because no date is involved.

Common uses

A time-between calculation answers questions about a work shift, a class, a drive, a flight, a meeting, a night's sleep or a recording. To convert either time into 24-hour or military notation, open the military time converter; to count down to a time that has not happened yet, use the time-until page.

How the calendar works

The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.
