Use a Formula to Count Days Since Date (Event)

[Say-Chi]

I have three columns:

1. Email
2. Sent (Yes/No)
3. Date (Sent)

I would like to add a fourth col to display the number of days since the email was sent (i.e. Current Date - Date Sent, displayed as Days). How can I write a formula for that?

Use DATETIME_DIFF():

Formula field reference

For an overview of formula fields, please refer to the Guide to Formula, Lookup, Count, and Rollup fields. Formulas may involve functions, numeric operations, logical operations, and text operation...

Also, I think you could remove the Sent field, cause you already have that information in Date field: if it is filled, it is send.

I would just do:

TONOW({Date Sent})
