how do you calculate the days between two dates

date2-date1

Leo

if i do that, the result is sometimes 3 days 1:00. even if i use number() the result is 3,04 or something. i already checked if the date has a time but it seems not like that. it shows 23.4.2017 0:00 for "Lieferdatum" and "Datum"

if i use this function to calculate the hours: (number(Lieferdatum) - number(Datum)) / 3600000, i get 73 (should be 72)

i already tried "datetime(date,0)"

Can it be that one of the data fields have the type datetime?

hey,

thanks for the reply. i checked it both and it's date not datetime.

Kind regards

Use this ninox fonction days(date1,date2)

This works as it should. Thank you very much!
