		int32_t *	iyear,
		int32_t *	iday,
		double *	sec
	)

◆ jdate()

int jdate	(	int32_t	julianDay,
		int32_t *	year,
		int32_t *	dayOfYear
	)

Takes in a julian day and mutates year and doy to contain the gregorian year and day of that gregorian year of that julian day.

Parameters

julianDay	The Julian day to be converted
year	Out-parameter indicating the gregorian year that `julianDay` is in
dayOfYear	Out-parameter indicating the number of days into the gregorian year that `julianDay` is.

◆ jday()

int32_t jday	(	int16_t	year,
		int16_t	month,
		int16_t	day
	)

Converts a calendar date to the corresponding Julian day starting at noon on the calendar date. Originally implemented by Frederick S. Patt, GSC, November 4 1992. [Van] Flandern and Pulkkinen, Ap. J. Supplement Series 41, November 1979, p. 400.

Parameters

year	4-digit year
month	1-12
day	1-31

Returns: The astronomical Julian day corresponding to the one starting at noon on the calendar day
