Chinese New Year (CNY) falls on 19th February this year. That's an unusually late date; CNY generally falls around the beginning of February.
CNY can also fall on 20th February, though that's only happened once in my lifetime.
a. When will CNY next fall on 20th February?
b. Can CNY ever fall on 21st February? If so, when will that happen next?

As a check to guard against half-hour variation of civil time from atomic time, I varied the time zone: instead of just 8 hours east of Greenwich, I also used -7.5 and -8.5. The middle column uses the 8-hour difference; all entries are marked with the time zone used. The only difference is that the 2148 event would go away if Delta T, as it's called would vary in one of the directions by 1/2 hour. However, 2148 is not that far away, as the other years, so it's less likely to have a half-hour discrepancy.
