Year

 
intyearintnDate
calendardateSystem )[inline]
Returns the year contained within a serial Julian date as an integer. This function uses dateYMD, to convert the serial Date into a day/ month/ year, from which the year is returned.

Example 1

#include <stdio.h>
#include <codecogs/units/date/year.h>
using namespace Units::Date;
 
int main()
{
  printf("\n The year is %d", year(1741667));               // The year is 0056
  printf("\n The year is %d", year(1841667, cal_Julian));   // The year is 0330
  return 0;
}

  • cal_Gregorian - n.b. there is an optimised year function for Gregorian dates.
  • cal_Julian - the only sensible mode (for the time being!!)
  • cal_Excel (same as Gregorian)

Note

It may be faster to simply use dateYMD, particularly if you also need the day and year from a date.

Parameters

nDateis a serial number of days from 24 November 4714 BC (1 January 4713BC in the Julian Calendar) - also known as the Julian Period.
dateSystemselects which date system should be used (see constants):

  printf("\n The year is %d", year(169304));         // The year is 2367
}

Note

If you require the day, month and year from the Julian Date it may be faster to simply use dateYMD, particularly if you need two or more parts of a date.
