In this system, the serial number 1 represents 1/1/1900 12:00:00 a.m. Times are stored as decimal numbers between .0 and .99999, where .0 is 00:00:00 and .99999 is 23:59:59. The date integers and time decimal fractions can be combined to create numbers that have a decimal and an integer portion. For example, the number 32331.06 represents the date and time 7/7/1988 1:26:24 a.m.

To help you perform complex date and time calculations, Excel includes many built-in date and time functions.

### The TODAY() Function and the NOW() Function

TheTODAYfunction returns the serial number of today's date based on your system clock and does not include the time. TheNOWfunction returns the serial number of today's date and includes the time.

#### How Dates Are Sorted Based on Serial Number

In Excel, dates are sorted based on the serial number of the date, instead of on the displayed number. Therefore, when you sort dates in Excel, you may not receive the results you expect.
