Unfortunately, it appears that I didn't get the right answer. Going back and rereading it (more carefully this time around), the desired date of New Years is:

  1/1  if 1/1 is Mon-Fri OR Sat
  1/2  if 1/1 is Sun

That's much more complicated. I found something that I thought would work...

 1*1:0:1:0:0:0*NBD,BD1,IBD,FD1   = New Year's Day (Saturday)
 1*1:0:1:0:0:0*NBD,BD1,NBD,FD2   = New Year's Day (Sunday observed Mon
+day)
 1*1:0:1:0:0:0*IBD               = New Year's Day (real)

but it is failing on some years. I actually think it might be a bug. I'll check into it tomorrow.

I have definitely decided that I need to add a couple more modifiers similar to IBD and NBD which will check if it is a given day of the week. That would make this much simpler. I hadn't been aware of the complexity of the holiday definition used here.

There was definitely a bug. I fixed it today and it will be in the next release (originally scheduled for tomorrow 12/1, but it will probably get pushed back a day or two to allow me to complete the work to get this working).

In the next release (6.52 which should be released tomorrow after a bit more testing), you will be able to define New Years the way you are asking in a couple of ways:

   # Saturday
   1*1:0:1:0:0:0*NBD,BD1,IBD,FD1   = New Year's Day
   # Sunday (observed Monday)
   1*1:0:1:0:0:0*NBD,BD1,NBD,FD2   = New Year's Day
   # M-F
   1*1:0:1:0:0:0*IBD               = New Year's Day
[download]

or

   # Saturday
   1*1:0:1:0:0:0*IW6               = New Year's Day
   # Sunday (observed Monday)
   1*1:0:1:0:0:0*IW7,FD1           = New Year's Day
   # M-F
   1*1:0:1:0:0:0*IBD               = New Year's Day
[download]

It's important to name the holiday the same for all definitions.

...And since I have the ear of "The Man", just a thought: the ability to input a hash or array of holidays would be powerful. Maybe through the constructor or a routine parameter? Say for example, if I want to keep a table of holidays in my sql db, then they could be maintained by a user through a web interface instead of an admin in a config file. Then I could query the db and input those days into the date object. Not that I spend waaaaay too much time thinking about holidays or anything.

Unless of course this functionality already exists and I missed it somewhere in the documentation dispite studying it for hours. If that's the case, then nevermind.

Simply beautiful.

Do you know how many YEARS this has plagued me? Now I can set it once and never touch it again. Since every single date routine I do involves holiday handling, this is the primary reason I use this module for everything. Thank you!

I was able to update the package on my Linux boxes and it's working perfectly. However, my Win2012 64bit ActiveState v5.20 ppm is only showing the latest available for Date::Manip is v6.50. Repository is set to http://ppm4.activestate.com/MSWin32-x64/5.20/2000/package.db.gz and showing a last check datetime of 12/2/2015 @ 13:11. Looking at the ActiveState, it's showing latest release is 6.52, but only 6.51 in the table.

Any idea how long until it's ready for ppm?

Sorry, I feel like I finally got my red rider bb gun for Christmas.
