Thought I'd seen something like this before, but couldn't find it

Updated 19 March 2018 to my current use because if new comments. Replaced 'dn' with 'dn3' to stop issues with Wednesdays and removed the extra entry for 'year'

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

This is my Custom Function and I want to edit it

Discuss:

There is a problem with your variables. If the day of the week is Wednesday, then using "dname" correctly calculates "Wednesday" but then the next substitution for "dn" re-writes the "dn" in Wednesday to "WeWedesday". It's easy enough to use a different variable name but I thought I would point out the problem.

I think I'd add 'm' (not padded) and 'd' (not padded). or perhaps I'd look at the way PHP handles date string functions (using the same "formats"):
http://php.net/manual/en/function.date.php
just to make it consistent in this function. So month would have 'F', 'm', 'M' or 't' choices.

make sure to add quotes around format.

date.format ( date ; "mm-dd-yyyy" )

Hi Tim, noticed that "year" is listed twice.

Thanks Richard. I had changed this in my solution along ago, removing the extra 'year'. But your comment and made me realise I had not updated this with the fix for wednesdays - now updated.
Beverly, I know next to nothing about php, I would imagine for those that would want consistency across their platforms they could easily follow what I have done here and tweak it for their own preference.
