Documentation
toOrdinalDate :: Day -> (Integer, Int) #
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 #
Convert from ISO 8601 Ordinal Date format. Invalid day numbers will be clipped to the correct range (1 to 365 or 366).
fromOrdinalDateValid :: Integer -> Int -> Maybe Day #
Convert from ISO 8601 Ordinal Date format.
Invalid day numbers return Nothing
showOrdinalDate :: Day -> String #
Show in ISO 8601 Ordinal Date format (yyyy-ddd)
isLeapYear :: Integer -> Bool #
Is this year a leap year according to the proleptic Gregorian calendar?
mondayStartWeek :: Day -> (Int, Int) #
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) #
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).
Arguments
| :: Integer | Year. |
| -> Int | Monday-starting week number (as |
| -> Int | Day of week.
Monday is 1, Sunday is 7 (as |
| -> Day |
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).
Arguments
| :: Integer | Year. |
| -> Int | Monday-starting week number (as |
| -> Int | Day of week.
Monday is 1, Sunday is 7 (as |
| -> Maybe Day |
Arguments
| :: Integer | Year. |
| -> Int | Sunday-starting week number (as |
| -> Int | Day of week
Sunday is 0, Saturday is 6 (as |
| -> 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).
Arguments
| :: Integer | Year. |
| -> Int | Sunday-starting week number (as |
| -> Int | Day of week.
Sunday is 0, Saturday is 6 (as |
