    Unhappy Date formula validation to True / False

    I entered a new date and column L is now showing up as False.

    Re: =date(2020,1,-2)-weekday(date(2020,1,3))+h12*7

    What cell has the formula you provided?

    What is the formula in column L?

    What is the logic of your formula? Why add a utilization to a date? Seems like adding apples and elephants.

    L - =AND($J$12>=J48,OR($K$12<=K48,K48=""))
    J - =DATE(2020,1,-2)-WEEKDAY(DATE(2020,1,3))+H12*7

    The dates shows when they start or end. So if they end, it should give a FALSE output. I added a start date and it should come out as TRUE

    Re: =date(2020,1,-2)-weekday(date(2020,1,3))+h12*7

    Excel calculates dates by counting the number of days since 1/1/1900.
    In cell J12, 44081 corresponds to the date 9/7/2020.
    The formula for L48 begins =AND($J$12>=J48...
    The date shown in the screenshot, 9/16/2020 (44090) is greater than 9/7/2020 (44081), so the AND function evaluates to false.
    Let us know if you have any questions.

    Re: =date(2020,1,-2)-weekday(date(2020,1,3))+h12*7

    Thank you! That makes sense! So I'm thinking I have to adjust the formula on

    J12 =DATE(2020,1,-2)-WEEKDAY(DATE(2020,1,3))+H12*7

    This is where I'm stuck. How do I change this formula so that when I add a new 'Start Date' result value is True; but when I add an 'End Date' the value returns False?

    Re: Date formula validation to True / False

    I see that the title above post #1 is different from the rest, so I assume that is the edited title, Thank You.
    I think that to answer the question of how to change the formula in cell J12 so that it meets the conditions "when I add a new 'Start Date' result value is True; but when I add an 'End Date' the value returns False" we would need to know the rational behind the formula and why the resulting date is used in the formula for L14:L48.
