I have IT acknowledgement form for users to sign off when they received laptops from me.
Instead of every time i type in the date, i set a cell using Today function:
1) Right click on the cell and select Format Cells…
2) Click on Number tab, select Date in the Category
3) Select the type of format you prefer, mine is 14-Mar-01
4) Type in the function =TODAY()
5) Every time i open this file, it will display current date.
