Subject: Re: Finding the last Sunday of a month

OK. Now, I've got that last Sunday's date in January. And, I've now 
delineated all of the successive Sundays thereafter. Each of them is a 
budgetary fencepost for me. So, can someone help me to determine what 
budget period, out of all 13 of them, that today's date, or any day for 
that matter, would fall into? I think that all of my budget dates below 
are actually strings, so, they don't parse with dates as they are.

Thanks,
Peter

Here's what I have now. It works. I just need to see what today, or any 
day, would fall into.

require 'date'
now = DateTime.now
year = now.year
d = Date.new(now.year, 2, 1)
d.to_s
d -= 1
d.to_s
d -= d.wday
i = d.wday
d.to_s
firstbudgetfence = d

t = Time.now
t = t.strftime("%Y-%m-%d")
budget1   = Date.new(now.year, 1, 1)
budget2   = firstbudgetfence
budget3   = firstbudgetfence + 28
budget4   = budget3 + 28
budget5   = budget4 + 28
budget6   = budget5 + 28
budget7   = budget6 + 28
budget8   = budget7 + 28
budget9   = budget8 + 28
budget10   = budget9 + 28
budget11   = budget10 + 28
budget12  = budget11 + 28
budget13  = budget12 + 28
