How do I make a formula to calculate the third Friday of the current month?

Here is a formula that will calculate the third Friday of the current month:

NextDayOfWeek( FirstDayOfMonth(Today()) - Days(1), 5 ) + Weeks(2)

It can be broken down to the following steps:

1) find the first day of the month containing today
2) go back one day to the last day of the previous month
3) find the next Friday (the number 5 represents Friday)
4) add two weeks to that to get the third Friday

You have to go back one day from the first day of the month because the function NextDayOfWeek() starts the search with the next day after the one given.

Formula for weekday without using Fridays

I am looking to create a formula that will calculate an installation date. The work can only be done during the work week, however the customer will not allow Friday work.


WeekdayAdd([Notification Date],+37)


However, I am not sure how to remove the Friday out of the weekday add. Any suggestions?


Thanks in advance

Hi Jason, You'll want your

Hi Jason,


You'll want your formula to detect when it's about to display a Thursday, and instead have it display the following day:




// If the day of the week 37 days after Notiifcation Date is a Thursday, that's not valid, so add an extra day.

DayOfWeek(WeekdayAdd([Notification Date], 37))=4,

WeekdayAdd([Notification Date], 38),


// Otherwise, just add 37 days as usual.

WeekdayAdd([Notification Date], 37)
