**LindaC88**I use calculation field "Number of days" on my form. There is also an extra field "Hours".

How can I set that number of days is calculated as 2 days if it is over 24 hours? Till now it calculates only by date.

For example, 1st of Septembet 10.00 - 2nd of Septembet 12.00 should be calculated as 2 days, because it is over 24 hours.

**Jim_R**You have to convert the difference between the date fields into Epoch time first (number of seconds) to get the remaining hours less than a day. If you need it to be broken down to just the number of days then number of hours, here's how you will do it.

1. Add 3

**Form Calculation Widgets**- 1 for the Epoch difference

- 1 for the Days

- 1 for the Hours

**(Date2-Date1)*86400**We just get the epoch difference in seconds that will be used in the calculation

3. Set the Days calculation as follows:

**floor(Epoch Difference0-9****/****86400****)**The floor() function rounds down the quotient so it's a whole number. This will represent the number of days.

4. Set the Hours calculation as follows:

**((Epoch Difference0-9****/****86400****)****-****Days0-9****)*********24**We had to subtract the floored quotient from the regular quotient to get the decimal place (or the remainder) of the division. Then we'll multiply it by

**24**(the number of hours there are in a day) to get the remaining hours.Here's a quick demo form with 2 Date Picker Fields similar to your current setup. I emulated the settings of the
