dateDiff

Returns the number of days between two serial Julian dates. Aside from adding clarity to your code, we can see few reasons for anyone to use this function directly, we only provide it for completeness against Excel. For something more involved see dateDiff360. We recommend that you make the necessary subtraction yourself, the entire function is only:

inline int dateDiff(int nDateStart, int nDateEnd)
{
  return nDateStart - nDateEnd;
}

Example:

#include <stdio.h>
#include <codecogs/units/date/date.h>
using namespace Units::Date;

void main()
{
printf("\n Difference=%d days", dateDiff(date("12-8-2004"), date("20-8-2004")));  // Difference=8 days
}
