I have in cell p4 the date:
2014-01-01 (obtained via formula (=(((O5/1000/60)/60)/24)+DATE(1970,1,1)))
I have in cell b5 the date:
2014-01-01 (typed in)
=(p4=b5) gives false
=(p4>=b5) gives false
How do I compare dates correctly in Excel?
You should be safe with chopping the parts up and reassembling them:
=DATE(YEAR(P4),MONTH(P4),DAY(P4))=DATE(YEAR(B5),MONTH(B5),DAY(B5))
- Select the two date cells.
- Press CTRL+1 to show the format tab
- On the Number tab, in the Format list, click Text
Perhaps there is a more appropriate comparison format, when you have dates in the format YYYY-MM-DD I think this one will work).
