To find 2nd Sunday of March

Ruby
1

All,
I have used the following code to find the second Sunday of march.
lastdate_of_march = Date.new(current_year, 3, 31)
i = lastdate_of_march.wday
second_sunday = Date.new(current_year, 3, (31- i -14))

is there any simple method to find Second Sunday of March.
If anyone knows kindly help me…

Regards,
Rajaa

Come on, that’s really not difficult. Start with the first day of
March and go from there. Knowing how many days there are in a week
should be sufficient. Note also, that you can use math operators on
Date instances (see “ri Date”).

Think about it like this (assuming that you don’t want to install the
chronic gem):

The second week is the 8th to the 14th of the month. Sunday is wday 0.

If the 14th is a Monday, which has a wday of 1, the second Sunday is
14-1=13th.

end_of_week_2 = Date.civil(Date.today.year, 3, 14)
second_sunday = end_of_week_2 - end_of_week_2.wday

Sunday is easiest with this method (because it is wday==0), but you
can generalize it to any day of the week.
