This blog is part of our Rails 5.2 series.
Before Rails 5.2, this is how we would write to find next or previous occurring day of the week.
Assume that current date is Tue, 27 Feb 2018.
# find previous thursday
>> Date.yesterday.beginning_of_week(:thursday)
=> Thu, 22 Feb 2018
# find next thursday
>> Date.tomorrow.end_of_week(:friday)
=> Thu, 01 Mar 2018
Rails 5.2 has introduced methods
Date#prev_occurring and Date#next_occurring to find next & previous
occurring day of the week.
# find previous thursday
>> Date.prev_occurring(:thursday)
=> Thu, 22 Feb 2018
# find next thursday
>> Date.next_occurring(:thursday)
=> Thu, 01 Mar 2018
