Adding the day of the week in letters (like 'Mon' for Monday) to your Excel dates can make your data clearer and easier to interpret at a glance. This feature simplifies tracking, planning, and scheduling by visually connecting dates to specific days. Here are some key benefits:

1. Improves Readability: Adding days in letters helps instantly recognize which day a date refers to without needing to calculate it mentally.
2. Reduces Errors: When you see the day name next to the date, you're less likely to make scheduling errors or data-entry mistakes.
3. Enhances Organization: Sorting and organizing tasks or events by day name helps you streamline weekly plans or reports.
4. Easy for Non-English Speakers: Adding day names in letters improves comprehension, especially for people learning Excel in a second language.

Mistake to Avoid: Don't Write Days in Letters Manually ⛔

Adding days in letters directly in a cell is a big mistake! 😡

Excel reads these cells as text, not numbers. This blocks calculations like finding the first day of the month or the previous Monday. However, Excel has the trick of adding days as text while keeping a numeric calculation format.
