# Re: [libreoffice-users] Calculate difference between two dates time)

```I was right about it not handling some dates, but was more complex than I
though. Put in a date that was 1 second short of a year, and it was bad.```
```
This seems to resolve the issue. Might have more rows than needed, Since
sometimes it has the correct results before the final row.
Again, pasted formulas to text editor, and change " " to _ and \t to ;
