Conversion with Day

dayToYearQuarter :: Day -> YearQuarter Source #

Extract Quarter from Day

>>> dayToYearQuarter (read "2017-02-03")
YearQuarter 2017 Q1

firstDayOfYearQuarter :: YearQuarter -> Day Source #

First day of the quarter.

>>> firstDayOfYearQuarter $ YearQuarter 2017 Q3
2017-07-01

lastDayOfYearQuarter :: YearQuarter -> Day Source #

Last day of the quarter

>>> lastDayOfYearQuarter $ YearQuarter 2017 Q1
2017-03-31

>>> lastDayOfYearQuarter $ YearQuarter 2016 Q2
2016-06-30

yearQuarterInterval :: YearQuarter -> Interval Day Source #

Day interval of month

>>> yearQuarterInterval $ YearQuarter 2017 Q2
2017-04-01 ... 2017-06-30
