Hi I need a Formula for difference in two dates for the whole column.
The first date is entered in A column and second date in B column and I need the result in C column.
There are around 1000 such entries so it goes from A1 - A1000. So, I was thinking if I can get one formula for the whole column.
ANother problem I am having is that MS Excel formulas are not working in calc..
I am working in dd/mm/yyyy format

=B1-A1 gets the difference between two numbers in unit days. Works in all spreadsheet including Excel.

Of course 99% of all Excel formulas do work when you simply load your Excel file into Calc.
I am working in dd/mm/yyyy format
Number formats have no influence on the values nor calculations.

Hi
Thanks for that but I need the formula to get the output in years, months and days.
I use this formula in Excel but its not working in Calc.
=YEAR(A2)-YEAR(A1)-IF(OR(MONTH(A2)<MONTH(A1),AND(MONTH(A2)=MONTH(A1), DAY(A2)<DAY(A1))),1,0)&" years, "&MONTH(A2)-MONTH(A1)+IF(AND(MONTH(A2)<=MONTH(A1),DAY(A2)<DAY(A1)),11,IF(AND(MONTH(A2)<MONTH(A1),DAY(A2)>=DAY(A1)),12,IF(AND(MONTH(A2)>MONTH(A1),DAY(A2)<DAY(A1)),-1)))&" months,"&A2-DATE(YEAR(A2),MONTH(A2)-IF(DAY(A2)<DAY(A1),1,0),DAY(A1))&" days"
and as I need it for the whole column so I thought if I could find a simploer solution than this formula...

It is too late at night for me to think of another formula, but the one you have seems to work if you change all of the commas to semicolons (except within your literal strings such as "years, ". At least I tried a few variations and the answer was correct.

Excel has (undocumented) DATEDIF, in Calc you can use additional functions MONTHS and YEARS.

Both applications don't know the respective other application's function, but there are compatible formulas made of common spreadsheet functions:
