Date range formula

naomi79266

I am trying to write a date range formula with an IF AND statement (I think). 

I need to check a box if [Previous date] is in a specific date range.

It should look something like this:

=IF(AND([Previous date]@row <= DATE(2019, 1, 31), [Previous date]@row >= DATE(2019, 1, 1)), 1, 0)

This one will flag all dates in January 2019. You'll need to adjust the dates manually. The 1 and 0 at the end of the formula turn the checkbox on and off.

When you only have two results (checked or unchecked), you really only need to specify what changes the default of unchecked to checked. You could leave the 0 off of the end of the formula and it will still work the same way. (Just FYI).

A few additional things to keep in mind that may or may not make things a little easier for you...

.

 To help with having to manually adjust dates within a formula (if you're anything like me you stand a good chance of a typo or fat fingering something haha), you could reference 3 (or 6) different cells depending on the type of breakdown you are looking for. Something along the lines of (column headers are bold)...

Helper          Start          End

Year

Month

Day

.

You could then use (assuming the Year row is row 1)

 

=DATE(Start$1, Start$2, Start$3)

.

This gives you the ability to edit your dates without having to edit your formula. If you are looking for weekly, monthly or yearly counts you could use 

=IF(WEEKNUMBER([Previous Date]@row) = *********, 1)

In the section of ********* you have a few options. You could enter a specific number, WEEKNUMBER(a cell reference that would contain a number), or WEEKNUMBER(a date using the DATE function which could also be manual entry or cell references).

.

=IF(MONTH([Previous Date]@row) = ************, 1)

.

=IF(YEAR([Previous Date]@row) = ***********, 1)

.

=IF(AND(YEAR([Previous Date]@row) = **********, MONTH([Previous Date]@row) = **********), 1)
