- *
- * This package defines a set of routines that convert calendar dates to
- * and from a serial day number (SDN).  The SDN is a serial numbering of
- * days where SDN 1 is November 25, 4714 BC in the Gregorian calendar and
- * SDN 2447893 is January 1, 1990.  This system of day numbering is
- * sometimes referred to as Julian days, but to avoid confusion with the
- * Julian calendar, it is referred to as serial day numbers here.  The term
- * Julian days is also used to mean the number of days since the beginning
- * of the current year.
- *
- * The SDN can be used as an intermediate step in converting from one
- * calendar system to another (such as Gregorian to Jewish).  It can also
- * be used for date computations such as easily comparing two dates,
- * determining the day of the week, finding the date of yesterday or
- * calculating the number of days between two dates.
- *
- * When using this software on 16 bit systems, be careful to store SDNs in
- * a long int, because it will not fit in the 16 bits that some systems
- * allocate to an int.
- *
- * For each calendar, there are two routines provided.  One converts dates
- * in that calendar to SDN and the other converts SDN to calendar dates.
- * The routines are named SdnTo<CALENDAR>() and <CALENDAR>ToSdn(), where
- * <CALENDAR> is the name of the calendar system.
- *
- * SDN values less than one are not supported.  If a conversion routine
- * returns an SDN of zero, this means that the date given is either invalid
- * or is outside the supported range for that calendar.
- *
- * At least some validity checks are performed on input dates.  For
- * example, a negative month number will result in the return of zero for
- * the SDN.  A returned SDN greater than one does not necessarily mean that
- * the input date was valid.  To determine if the date is valid, convert it
- * to SDN, and if the SDN is greater than zero, convert it back to a date
- * and compare to the original.  For example:
- *
- *    int y1, m1, d1;
- *    int y2, m2, d2;
- *    long int sdn;
- *    ...
- *    sdn = GregorianToSdn(y1, m1, d1);
- *    if (sdn > 0) {
- *        SdnToGregorian(sdn, &y2, &m2, &d2);
- *        if (y1 == y2 && m1 == m2 && d1 == d2) {
- *            ... date is valid ...
- *        }
- *    }
- *
