toOrdinalDate :: Day -> (Integer, Int) | Source
convert to ISO 8601 Ordinal Date format. First element of result is year (proleptic Gregoran calendar), second is the day of the year, with 1 for Jan 1, and 365 (or 366 in leap years) for Dec 31.
fromOrdinalDate :: Integer -> Int -> Day | Source
convert from ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).
showOrdinalDate :: Day -> String | Source
show in ISO 8601 Ordinal Date format (yyyy-ddd)
isLeapYear :: Integer -> Bool | Source
Is this year a leap year according to the proleptic Gregorian calendar?
mondayStartWeek :: Day -> (Int, Int) | Source
Get the number of the Monday-starting 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`).
sundayStartWeek :: Day -> (Int, Int) | Source
Get the number of the Sunday-starting 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`).
fromMondayStartWeek | Source

-> Int | Monday-starting week number.
-> Int | Day of week. Monday is 1, Sunday is 7 (as "%u" in `formatTime`).

The inverse of `mondayStartWeek`. Get a `Day` given the year, the number of the Monday-starting 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" in `formatTime`).
fromSundayStartWeek | Source
:: Integer | Year.
-> Int | Sunday-starting week number.
-> Int | Day of week Sunday is 0, Saturday is 6 (as "%w" in `formatTime`).
-> Day |
The inverse of `sundayStartWeek`. Get a `Day` given the year and the number of the day of a Sunday-starting week. The first Sunday is the first day of week 1, any earlier days in the year are week 0 (as "%U" in `formatTime`).
