val day_of_week : Core_kernel__.Date0.t -> Core_kernel.Day_of_week.t

Only accurate after 1752-09

val week_number_and_year : Core_kernel__.Date0.t -> Base.Int.t * Base.Int.t

Week of the year, from 1 to 53, along with the week-numbering year to which the week belongs. The week-numbering year may not correspond to the calendar year in which the provided date occurs.

According to ISO 8601, weeks start on Monday, and the first week of a year is the week that contains the first Thursday of the year. This means that dates near the end of the calendar year can have week number 1 and belong to the following week-numbering year, and dates near the beginning of the calendar year can have week number 52 or 53 and belong to the previous week-numbering year.

The triple (week-numbering year, week number, week day) uniquely identifies a particular date, which is not true if the calendar year is used instead.

val week_number : Core_kernel__.Date0.t -> Base.Int.t

See week_number_and_year for the meaning of week number.

val is_weekend : Core_kernel__.Date0.t -> Base.Bool.t

val is_weekday : Core_kernel__.Date0.t -> Base.Bool.t

val is_business_day : 
  Core_kernel__.Date0.t ->
  is_holiday:(Core_kernel__.Date0.t -> Base.Bool.t) ->
  Base.Bool.t

Monday through Friday are business days, unless they're a holiday.

val add_days : Core_kernel__.Date0.t -> Base.Int.t -> Core_kernel__.Date0.t

add_days t n adds n days to t and returns the resulting date.

Inaccurate when crossing 1752-09.

val add_months : Core_kernel__.Date0.t -> Base.Int.t -> Core_kernel__.Date0.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.

In particular, this means adding x months and then adding y months isn't the same as adding x + y months, and in particular adding x months and then -x months won't always get you back where you were. *

val add_years : Core_kernel__.Date0.t -> Base.Int.t -> Core_kernel__.Date0.t

add_years t n has the same semantics as add_months for adding years to Feb 29 of a leap year, i.e., when the addition results in a date in a non-leap year, the result will be Feb 28 of that year.

val diff : Core_kernel__.Date0.t -> Core_kernel__.Date0.t -> Base.Int.t

diff t1 t2 returns date t1 minus date t2 in days.

val diff_weekdays : 
  Core_kernel__.Date0.t ->
  Core_kernel__.Date0.t ->
  Base.Int.t

diff_weekdays t1 t2 returns the number of weekdays in the half-open interval [t2,t1) if t1 >= t2, and - diff_weekdays t2 t1 otherwise.

val diff_weekend_days : 
  Core_kernel__.Date0.t ->
  Core_kernel__.Date0.t ->
  Base.Int.t

diff_weekend_days t1 t2 returns the number of days that are weekend days in the half-open interval [t2,t1) if t1 >= t2, and - diff_weekend_days t2 t1 otherwise.

val add_weekdays_rounding_backward : 
  Core_kernel__.Date0.t ->
  Base.Int.t ->
  Core_kernel__.Date0.t

First rounds the given date backward to the previous weekday, if it is not already a weekday. Then advances by the given number of weekdays, which may be negative.

val add_weekdays_rounding_forward : 
  Core_kernel__.Date0.t ->
  Base.Int.t ->
  Core_kernel__.Date0.t

First rounds the given date forward to the next weekday, if it is not already a weekday. Then advances by the given number of weekdays, which may be negative.

val add_business_days_rounding_backward : 
  Core_kernel__.Date0.t ->
  is_holiday:(Core_kernel__.Date0.t -> Base.Bool.t) ->
  Base.Int.t ->
  Core_kernel__.Date0.t

First rounds the given date backward to the previous business day, i.e. weekday not satisfying is_holiday, if it is not already a business day. Then advances by the given number of business days, which may be negative.

val add_business_days_rounding_forward : 
  Core_kernel__.Date0.t ->
  is_holiday:(Core_kernel__.Date0.t -> Base.Bool.t) ->
  Base.Int.t ->
  Core_kernel__.Date0.t

First rounds the given date forward to the next business day, i.e. weekday not satisfying is_holiday, if it is not already a business day. Then advances by the given number of business days, which may be negative.

val add_weekdays : Core_kernel__.Date0.t -> Base.Int.t -> Core_kernel__.Date0.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 :

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.

If you don't want to skip Saturday or Sunday, use add_days_skipping.

val add_days_skipping : 
  Core_kernel__.Date0.t ->
  skip:(Core_kernel__.Date0.t -> Base.Bool.t) ->
  Base.Int.t ->
  Core_kernel__.Date0.t

add_days_skipping t ~skip n adds n days to t, ignoring any date satisfying skip, starting at the first date at or after t that does not satisfy skip. For example, if skip t = true, then add_days_skipping t ~skip 0 > t.

add_business_days and add_weekdays are special cases of add_days_skipping.

  on:Core_kernel.Day_of_week.t ->
  Core_kernel__.Date0.t

first_strictly_after t ~on:day_of_week returns the first occurrence of day_of_week strictly after t.

val days_in_month : year:Base.Int.t -> month:Core_kernel.Month.t -> Base.Int.t

days_in_month ~year ~month returns the number of days in month, using year only if month = Month.Feb to check if there is a leap year.

Incorrect for September 1752.

val is_leap_year : year:Base.Int.t -> Base.Bool.t

is_leap_year ~year returns true if year is considered a leap year

module Days = Core.Date.Days

Days provides a linear representation of dates that is optimized for arithmetic on the number of days between dates, rather than for representing year/month/day components. This module is intended for use only in performance-sensitive contexts where dates are manipulated more often than they are constructed or deconstructed; most clients should use the ordinary t.
