years_day

include datetime.e -- (default namespace is datetime) 
public function years_day(datetime dt) 

Gets the Julian day of year of the supplied date.

Parameters:

1. dt : a datetime to be queried.

Returns:

An integer, between 1 and 366.

Comments:

For dates earlier than 1800, this routine may give inaccurate results if the date applies to a country other than United Kingdom or a former colony thereof. The change from Julian to Gregorian calendar took place much earlier in some other European countries.

Example 1:

include std/datetime.e 
 
datetime d = new(2008, 5, 2, 0, 0, 0) 
integer day = years_day(d) 
? day 

Results:
