So I have a method that I was using to calculate Mother's day. And it was working fine until we ticked over to the month of May.

Calling this May works fine now:

2.1.2 :023 > Time.now
 => 2015-05-06 11:08:30 +1000 
2.1.2 :024 > Chronic.parse("2nd Sunday this May")
 => 2015-05-10 12:00:00 +1000 

But something strange happens when I ask for the 2nd Sunday of next May

2.1.2 :025 > Chronic.parse("2nd Sunday of next May")

I could understand if it returned May 2016, but it's not setting the month at all.

Had a look through the source and I am not sure how this is happening… looks a little out of my league though, so not sure if I could contribute a bugfix.

Don't worry about fixing, there's ongoing rewrite of large part of Chronic and I know how big mess current code is. Also actually this is fixed in my rewrite branch

Chronic.parse("2nd Sunday of next May", :guess => false)
=> 2016-05-08 00:00:00 +0300...2016-05-09 00:00:00 +0300

But that rewrite isn't finished and I'll have time to continue work on it only in autumn. So for now you'll have to somehow workaround it yourself.
