Identify the Date of the 13th Working Date of Every Month

Hi All

 

Im looking for a way of indentifying the 13th Working day of every month.

 

Assume the Day 1 is the 1st working day of a month and some examples below

 

  • So if we look at September the 13th working day was  Thursday 14th  September
  • So if we look at October  the 13th working day is   Wednesday  18th  October
  • So if we look at November  the 13th working day is   Thursday   16th  November

 

Data Source

 

Column 1 Data can be as simple as 01/01/2023 to 31/12/2023

 

Column 2 would be a formula that would flag what day is the 13th Working Day of Each Month?

 

e.g

 

 

 

 

 

Date	13th Working Day
Sun 01/01/2023	NA
Mon 02/01/2023	NA
Tue 03/01/2023	NA
Wed 04/01/2023	NA
Thu 05/01/2023	NA
Fri 06/01/2023	NA
Sat 07/01/2023	NA
Sun 08/01/2023	NA
Mon 09/01/2023	NA
Tue 10/01/2023	NA
Wed 11/01/2023	NA
Thu 12/01/2023	NA
Fri 13/01/2023	NA
Sat 14/01/2023	NA
Sun 15/01/2023	NA
Mon 16/01/2023	NA
Tue 17/01/2023	NA
Wed 18/01/2023	13th Working Day January

 

 

 

Any help comments or approqaches would be appreciated

    If your weekend is Saturday and Sunday, some of your examples are incorrect. Without taking public holidays into account, the 13th working day can only be the 17th, 18th or 19th day of the month.

    In B2:

    =IF(A2=WORKDAY(EOMONTH(A2,-1),13),"13th Working Day", "")

    Fill down.

      HansVogelaar    Apologies for not replying.  Your formula worked a treat.  It blew my mind.

       

      A big thanks for the assistance.
