Display a message if today's date is in a linked field

This can be done using the FIND() function. Since you’re working with dates this could be tricky. Your date field appears to use the 'MMMM D, YYYY' format. So, you want to test if Today’s date can be “found” in the {Absences} field. I included the SET_TIMEZONE() function in my formula below, but you may need to adjust the timezone to the one that matches your location.

IF(
   FIND(
      DATETIME_FORMAT(SET_TIMEZONE(NOW(), 'America/Los_Angeles'), 'MMMM D, YYYY'), 
      {Absences}
   ),
   "Yes"
)

Edited: Formula edited to replace TODAY() with NOW()

IF(
   FIND(
      DATETIME_FORMAT(SET_TIMEZONE(NOW(), 'America/Los_Angeles'), 'MMMM D, YYYY'), 
      {Absences}
   ),
   "Yes"
)

Thanks! That doesn’t quite seem to work. It’s behaving erratically:

Is the primary field of whatever table {Absences} links to an actual date field? Did you adjust for the correct timezone?

Yes, Absences is linked to these rows in another table:

And did you do that^?

Yup! I’m not sure why this isn’t working, I’ve tried several different formulas/formats. It’s quite odd.

That did it! Thank you!!
