4. Click OK.

Long Date Format

Note: to apply a Time format, in the Category list, select Time.

5. Dates are stored as numbers in Excel and count the number of days since January 0, 1900. Times are handled internally as numbers between 0 and 1. To clearly see this, change the number format of cell A1, B1 and C1 to General.

General Format

Note: apparently, 41083 days after January 0, 1900 is the same as June 23, 2012. 6:00 is represented as 0.25 (quarter through the day).

6. You can enter times as 6:00, but Excel displays this time as 6:00:00 AM in the formula bar. AM is used for times in the night and morning. PM is used for times in the afternoon and evening.

Time Format

7. Change the number format of cell C1 to Date only.

Date Format

Note: cell C1 still contains the number 41083.25. We only changed the appearance of the number, not the number itself.

8. Finally, if you cannot find the right date or time format, create a custom date or time format.
