Excel Date and Time Functions

This page lists the built-in Excel Date and Time Functions.

If you are not familiar with the way that Excel stores dates and times as numeric values, you may find it useful to read the Excel Dates and Times page, before working with dates and times in Excel.

The functions listed below are grouped into categories, to help you to find the function you need. Selecting a function name will take you to a full description of the function, with examples and details of common errors.

Note that some of the Excel Date & Time functions are new to Excel 2010 or Excel 2013, so are not available in earlier versions of Excel.
