Today’s date

I know that today it is 2/10/2021 but I'd like to see it in Excel. To see todays date just use =TODAY() date formula. You will see year, month and day.

To see the number of month use =MONTH(NOW()) or =MONTH(TODAY())

The same with year =YEAR(NOW()) or =YEAR(TODAY())

How many days between dates?

This time it is all about cell date formatting.

To calculate days between 2 dates just type them in cells (formatted as date) and then just substract cells =B2-B1 in the cells formatted as number or general.

The rule is simple:

  • when you want to see date - format as date
  • to see number - format as number of general

Days from today

To calculate future date which will be after given number of days just sum TODAY date and the number. Excel today formula is =TODAY()+30

=TODAY()+60 - 60 days from today

=TODAY()+90 - 90 days from today

=TODAY()+120 - 120 days from today

=TODAY()+150 - 150 days from today

=TODAY()+180 – 180 days from today

=TODAY()+1000 – 1000 days from today

=TODAY()+10000 – 10000 days from today

=TODAY()+1000000 – 1000000 days from today

 

There will be 4759 year 1 million days from now!
