Custom date formats in Excel allow you to display only certain parts of the date.
Say you had a date of 18/02/1979, which coincides to be my birthday 🙂
You can use the Format Cells dialogue box to show only the number 18, the day that corresponds to that date (Sunday), the month as a number on in abbreviated form and the year in two or four digits.
You cam also mix and match to create a custom date format or even enter a custom text that would show something like: Today is Sunday
You can download the following workbook which shows you the different formats that you can use and see the tutorial below of how this can be easily achieved.
