In Excel, dates and times are stored internally as numbers. These are only converted to legible dates and times when you format the cell using a date or time format. The following table lists the formatting codes that are specific to dates and times. You use these codes when you are creating a custom display format (Format | Cells | Number tab | Custom).
| Symbol | Meaning | |
|---|---|---|
| m | Displays the month or minutes as a number without a leading 0 | |
| mm | Displays the month or minutes as a number with a leading 0 | |
| mmm | Displays the month as abbreviated text (Jan, Feb, Mar, and so on) | |
| mmmm | Displays the month as text (January, February, March, and so on) | |
| d | Displays the day of the month as a number without a leading 0 | |
| dd | Displays the day of the month as a number with a leading 0 | |
| ddd | Displays the day of the week as abbreviated text (Sun, Mon, Tue, and so on) | |
| dddd | Displays the day of the week as text (Sunday, Monday, Tuesday, and so on) | |
| yy | Displays the year with two digits | |
| yyyy | Displays the year with four digits | |
| h | Displays the hour without a leading 0 | |
| hh | Displays the hour with a leading 0 | |
| s | Displays the seconds without a leading 0 | |
| ss | Displays the seconds with a leading 0 | |
| [ ] | When surrounding hours, minutes, or seconds place holders, displays hours greater than 24 or minutes and seconds greater than 60 | |
| AM am PM pm A a P p | Uses a 12-hour clock, displaying AM or PM as specified | |
| \ | Forces display of the following character | |
| . (period) | The decimal point. | |
| "text" | Displays the text within the quotes. |
To understand better the effect of the date and time codes, take a look at the following information, which shows several common date and time formats and how they affect numbers.
| Category | Format | Value | Displayed As | |||
|---|---|---|---|---|---|---|
| Date | m/d/yy | 34369 | 2/4/94 | |||
| d-mmm-yy | 34409 | 16-Mar-94 | ||||
| Time | h:mm AM/PM | 0.654166667 | 3:42 PM | |||
| [h]:mm:ss | 2.592673611 | 62:13:27 |
Notice that the numbers shown in the value column of these examples are the internal values stored by Excel for dates and times.
