`of_string s` accepts three-character abbreviations and full day names with any capitalization, and strings of the integers 0-6.

    val to_string_long : t -> string

Capitalized full day names rather than all-caps 3-letter abbreviations

    val of_int_exn : int -> t

These use the same mapping as `Unix.tm_wday`: 0 <-> Sun, ... 6 <-> Sat

    val of_int : int -> t option

    val to_int : t -> int

    val iso_8601_weekday_number : t -> int

As per ISO 8601, Mon->1, Tue->2, ... Sun->7

    val shift : t -> int -> t

This goes forward (or backward) the specified number of weekdays

    val num_days : from:t -> to_:t -> int

`num_days ~from ~to_` gives the number of days that must elapse from a `from` to get to a `to_`, i.e. the smallest non-negative number `i` such that `shift from i = to_`.

    val is_sun_or_sat : t -> bool

    val all : t list

    val weekdays : t list

`Mon; Tue; Wed; Thu; Fri`

    val weekends : t list

`Sat; Sun`
