 Notes 

  • A cell may display ##### when it contains data that has a number format that is wider than the column width. To increase the width of the column, select it, point to Column on the Format menu, and then click AutoFit Selection.
  • When a date or time is typed in a cell, it appears either in a default date or time format or in a format that was applied to the cell before the date or time was typed. (The default date or time format is based on settings in the regional settings in Control Panel.) If the default date settings are changed, any existing dates or times in your workbooks that are not formatted with the Format Cells command also change.
  • If you want to use the default date or time format, click the cell that contains the date or time, and then press CTRL+SHIFT+# or CTRL+SHIFT+@.
  • If you don't find the format you're looking for in the Type list, you can create a custom number format by using format codes for dates and times. For more information, click Create or delete a custom number format, or explore the following custom date and time codes.

ShowCustom date and time codes

Days, months, and years     If you use "m" immediately after the "h" or "hh" code or immediately before the "ss" code, Microsoft Excel displays minutes instead of the month.

To display Use this code
Months as 1–12 m
Months as 01–12 mm
Months as Jan–Dec mmm
Months as January–December mmmm
Months as the first letter of the month mmmmm
Days as 1–31 d
Days as 01–31 dd
Days as Sun–Sat ddd
Days as Sunday–Saturday dddd
Years as 00–99 yy
Years as 1900–9999 yyyy


Hours, minutes, and seconds

To display Use this code
Hours as 0–23 H
Hours as 00–23 hh
Minutes as 0–59 m
Minutes as 00–59 mm
Seconds as 0–59 s
Seconds as 00–59 ss
Hours as 4 AM h AM/PM
Time as 4:36 PM h:mm AM/PM
Time as 4:36:03 P h:mm:ss A/P
Elapsed time in hours; for example, 25.02 [h]:mm
Elapsed time in minutes; for example, 63:46 [mm]:ss
Elapsed time in seconds [ss]
Fractions of a second h:mm:ss.00


AM and PM     If the format contains an AM or PM, the hour is based on the 12-hour clock, where "AM" or "A" indicates times from midnight until noon and "PM" or "P" indicates times from noon until midnight. Otherwise, the hour is based on the 24-hour clock. The "m" or "mm" code must appear immediately after the "h" or "hh" code or immediately before the "ss" code; otherwise, Microsoft Excel displays the month instead of minutes.

  • When you try to undo a date or time format by selecting General in the Category list, Excel displays a number code. When you enter a date or time again, Excel displays the default date or time format. To enter a specific date or time format, such as January 2005, you may want to format it as text by selecting Text in the Category list.
