Module Date0

module Date0: sig .. end
converts a string to a date, in formats: * m/d/y * y-m-d (* valid iso8601_extended *) * DD MMM YYYY * DDMMMYYYY * YYYYMMDD
type t = private {
   y : int;
   m : Core_kernel.Std.Month.t;
   d : int;
}

val create_exn : y:int -> m:Core_kernel.Std.Month.t -> d:int -> t
create_exn ~y ~m ~d creates the date specified in the arguments. Arguments are validated, and are not normalized in any way. So, days must be within the limits for the month in question, numbers cannot be negative, years must be fully specified, etc.

val is_weekend : t -> bool
val is_weekday : t -> bool
val is_business_day : t -> is_holiday:(t -> bool) -> bool
val add_days : t -> int -> t
val add_months : t -> int -> t
add_months t n returns date with max days for the month if the date would be invalid. e.g. adding 1 month to Jan 30 results in Feb 28 due to Feb 30 being an invalid date, Feb 29 is returned in cases of leap year. *
val diff : t -> t -> int
diff t1 t2 returns date t1 minus date t2 in days.
val add_weekdays : t -> int -> t
add_weekdays t 0 returns the next weekday if t is a weekend and t otherwise. Unlike add_days this is done by looping over the count of days to be added (forward or backwards based on the sign), and is O(n) in the number of days to add. Beware, add_weekdays sat 1 or add_weekdays sun 1 both return the next tue, not the next mon. You may want to use following_weekday if you want the next following weekday, following_weekday (fri|sat|sun) would all return the next mon.
val add_business_days : t -> is_holiday:(t -> bool) -> int -> t
add_business_days t ~is_holiday n returns a business day even when n=0. add_business_days ~is_holiday:(fun _ -> false) ... is the same as add_weekdays. Use Pnl_db.Calendar_events.is_holiday as a conveninent holiday function.
val dates_between : min:t -> max:t -> t list
val business_dates_between : min:t -> max:t -> is_holiday:(t -> bool) -> t list
val weekdays_between : min:t -> max:t -> t list
val previous_weekday : t -> t
val following_weekday : t -> t
val first_strictly_after : t -> on:Core_kernel.Std.Day_of_week.t -> t
first_strictly_after t ~on:day_of_week returns the first occurrence of day_of_week strictly after t.
