If you calculate the date, then you calculate the Gregorian calendar: 19** year * month * day 1 1: 30.
If you count the lunar calendar, you are: * * year-month-day.
If possible, you can make the specific date clear and I'll help you figure it out.
Count the next day, because you are going to celebrate the Lunar New Year's birthday, and it is already the early morning of the next day.
