Description:

Just like the function Barbecue posted. But not recursive, so a bit faster for longer periods of time.

The dates in the example above are specified this way to avoid confusion between european and american date notation. Use normal date fields in your caculations!

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

I haven't tested this, but I don't see the need. How can it possibly work without the dayname function?

If you have 4 days between two dates for example, if the start date is Monday then you have 4 weekdays; if it's friday, you have 2. So how could you get this right without using the dayname function?

I had a hard time getting the recursive functions to work. This one saved me! Thanks!

Doesn't always calculate correctly.
Take 1st April 2015 to 30th April 2015.
It should be 22 days; but it calculates 21.

Has an error, Put in 10/10/2014 and 10/22/2014 and it returns 8, but should return 9 days.
