Sample input:
Weekdays ( dec 29 2004 ; jan 10 2005 )
Sample output:
8

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

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!

 databaser, CADec 3, 2011 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?
 brad, El SegundoJan 21, 2014 I had a hard time getting the recursive functions to work. This one saved me! Thanks!
 Ariel, 95134Feb 3, 2014 Really appreciate this feedback! I was not able finalize my formula until I saw this one. Thank you!
 Philip McGeehan, SMD LtdJun 18, 2015 Doesn't always calculate correctly. Take 1st April 2015 to 30th April 2015. It should be 22 days; but it calculates 21.
 Peter, Norristown, PAAug 25, 2015 Has an error, Put in 10/10/2014 and 10/22/2014 and it returns 8, but should return 9 days.
 Tom FitchSep 11, 2018 To those saying it calculates one day less than you expect -- that's not an error. You're wanting it to count the total number of weekdays. But this is counting the *difference* between the two dates. Tomorrow - today = 1, not 2. Seems to work well. To databaser's comment, DayName has nothing to do with it. It's math.
