“7:45 PM”) or as decimal numbers (e.g.

To work with hour values larger than 24, use a formula toconvert time to decimal hours.

For example:

Example #2 - Minutes ignored

The HOUR function ignores minutes and seconds.

When given a date that includes time, the HOUR function will extract the hour and ignore the date.

If the date contains no time value, HOUR returns 0 (zero) which is midnight.

The TIME function is useful when you want to assemble a proper time inside another formula.
