Function Documentation

Returns the number of days in the months of a Gregorian calendar for the month of year. The year is used to apply adjustments for leap years.

Each month has a fixed number of days, except in a leap year, when February gains an extra day. Although we traditionally treat the 29th February as the leap day, a left over remnant of the Roman calendar means that the theoretical leap day occurs on the 24th February - many celebrations occur on this day for this reason.

The number of days in each month of the Gregorian / Julian calendar are:

Example 1:

To output the number of days in each month of 1974

#include <stdio.h>
#include <codecogs/units/date/daysinmonth.h>

int main()
{
  for(int i=1;i<=12;i++)
    printf("\n Month %d has %d days",i , Units::Date::daysInMonth(2004,i));
  return 0;
}

Parameters:

year	can be any integer greater than 4800 BC (see isLeapYear).
month	can be any integer between 1 and 12 (inclusive).
