These operator/ overloads provide a conventional syntax for the creation of Proleptic Gregorian calendar dates.

For creation of a full date, any of the following three orders are accepted:

year/month/day,
month/day/year,
day/month/year.

In each case day can replaced with one of:

std::chrono::last, for the last day of the month;
weekday[i], for the i^th weekday of the month;
weekday[std::chrono::last], for the last weekday of the month.

A plain integer is accepted if its meaning is unambiguous from the types of other operands: 2005y/4/5 is allowed, but 5/April/2005 is not.

Partial-date types (year_month, month_day, etc.) can be created by not applying the second operator/ in any of the three orders.

[edit] Return value [edit] Example

#include <chrono>
using namespace std::chrono;
 
constexpr auto ym{2021y/8};
static_assert(ym == year_month(year(2021), August));
 
constexpr auto md{9/15d};
static_assert(md == month_day(September, day(15)));
 
constexpr auto mdl{October/last};
static_assert(mdl == month_day_last(month(10)));
 
constexpr auto mw{11/Monday[3]};
static_assert(mw == month_weekday(November, Monday[3]));
 
constexpr auto mwdl{December/Sunday[last]};
static_assert(mwdl == month_weekday_last(month(12), weekday_last(Sunday)));
 
// Those 3 year/month/day orders that people actually use on this planet and beyond:
constexpr auto ymd{year(2021)/January/day(23)};
static_assert(ymd == month{1}/23/2021);
static_assert(ymd == day{23}/1/2021);
static_assert(ymd == year_month_day(2021y, month(January), 23d));
