    Find how many Fridays in each month

    Hi,
    I have this file that was done by someone. It works if the year is 1900. This function shows in sheet2 (original)

    In line 2 of "Sheet2 (2)", B1 and A2, I change the year from 1900 to 2018. then B2:E2 prompt "#NUM!" error.

    In January there are 4 Fridays in 1/5, 1/12, 1/19. 1/26.

    Please advise

    Hi,
    There is an issue. The number of Fridays does not much the months (2018) in the calendar.

    Please advise.

    Perhaps =NETWORKDAYS.INTL(EOMONTH(B$1,-1)+1,EOMONTH(B$1,0),"1111011") would be a better suggestion, this will work with any date in B1, not just the 1st of the month.

    Re: Find how many Fridays in each month

    Hi jason,
    Your formula gives incorrect numbers of Fridays. I copied the formula
    to B4, then to C4:M4. For example in March, there should ne 5 Fridays, but the formula
    gives 4 Fridays. Please see the comparison in row 6 and row 12 in the attachment.

    Thanks

    The formula is correct for the date in the attachment. March 2009 had 4 Fridays!

    You are right. My mistake I did not check the month-year, rhe year should be 2018, not 2009. I change the years.
    Now it matches!

    Thanks
