Work days left (Excel / Numbers)

Hi there

I wan't an app - or something like that - that can tell me how many work days that are left from today to an other specified date.

I've Googled it, but i simply can't seem to find anything that can do this.
I found a little app called Days Left, but that only works with the total amount of days and doesn't exclude weekends and holidays.

I've succesfully made a spreadsheet in both Excel and Numbers (to check which was better) that can do this for me. With Quick Look it's almost like the little app that i wanted.

The problem is, that (lazy as i am) i don't wan't to open up the spreadsheet every day, so Excel or Numbers can refresh the =Today() formula and thus give me the right date in Quick Look.


Are there any ways i can have the spreadsheet update when Quick Look'ing it or in any other way without having to start up the program itself every time?
If anyone actually knows of a little app that can, in fact, do these things for me, please let me know too!


Thanks a bunch

 

Thanks, but wouldn't that keep Excel open also at all times then (taking up memory)?

 

That's actually pretty nice ergdegdeg.

Thanks a lot!
