Day of year, in range 1 (January 1st) to 366. December 31st is 365 in a common year, 366 in a leap year.
type WeekOfYear = Int Source #
Week of year, by various reckonings, generally in range 053 depending on reckoning.
isLeapYear :: Year > Bool Source #
Is this year a leap year according to the proleptic Gregorian calendar?
fromOrdinalDate :: Year > DayOfYear > Day Source #
Convert from ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).
pattern YearDay :: Year > DayOfYear > Day Source #
Bidirectional abstract constructor for ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).
fromOrdinalDateValid :: Year > DayOfYear > Maybe Day Source #
Convert from ISO 8601 Ordinal Date format.
Invalid day numbers return Nothing
showOrdinalDate :: Day > String Source #
Show in ISO 8601 Ordinal Date format (yyyyddd)
mondayStartWeek :: Day > (WeekOfYear, Int) Source #
Get the number of the Mondaystarting week in the year and the day of the week.
The first Monday is the first day of week 1, any earlier days in the year are week 0 (as %W
in formatTime
).
Monday is 1, Sunday is 7 (as %u
in formatTime
).

Get the number of the Sundaystarting week in the year and the day of the week.
The first Sunday is the first day of week 1, any earlier days in the year are week 0 (as %U
in formatTime
).
Sunday is 0, Saturday is 6 (as %w
in formatTime
).

The inverse of mondayStartWeek
. Get a Day
given the year,
the number of the Mondaystarting week, and the day of the week.
The first Monday is the first day of week 1, any earlier days in the year
are week 0 (as %W
