Apart from the Format Cells feature, you can also apply formulas to format date as abbreviated day of weeks or abbreviated months in Excel. Please do as follows:

Select a blank cell beside original dates, enter the formula =TEXT(A2,"MMM") (A2 is the date cell you will show as abbreviated day of weeks or months) into it, and then drag this cell’s AutoFill Handle to the range as you need.

Notes:
(1) For formatting dates as abbreviated month with only one letter, such as J, please apply this formula =LEFT(TEXT(A2,"MMM"),1).
(2) For formatting dates as abbreviated day of week, please apply these formulas: =TEXT(A2,"DDD") or =CHOOSE(WEEKDAY(A2), "Su", "M", "Tu", "W", "Th", "F", "Sa").

Formula is too complicated to remember? Save the formula as an Auto Text entry for reusing with only one click in future! Read more…     Free trial
