Calendar days, including weekends and holidays. Adding zero returns the original date; this is not a working-day calculation.
Chinese lunar conversion: 1950–2035. Gregorian calculations: 1900–2199. Leap months remain distinct from regular months.
Dates follow the regular Chinese lunar month. Chinese New Year's Eve is the day before the next lunar year, so it is not always day 30. Check official local announcements separately for public holidays.
