"The Kangxi Emperor's reign of 61 years" ... hmm 5 Feb 1661 to 20 Dec 1722 .. beginning of 1661 to beginning of 1662 is one year,  1662 - 1661 = 1. So beginning 1661 to beginning 1722 would be 1722 - 1661 = 61, but he served until the end of 1722, not the beginning, so add that additional year, so it is 62 years. 2A01:E0A:5C0:7160:244C:E4B3:B50D:709E (talk) 13:40, 20 September 2022 (UTC)
