20 10 Lunar New Year high tide time is June 29th.

"There are two tides on the fifteenth day of the first lunar month, and the tide rises at noon in July and August 234." This means that the tide rises at six o'clock in the morning and six o'clock in the evening on the fifteenth day of the lunar calendar, and then it is delayed for more than 50 minutes every day until the tide rises at noon in July, August and 234, and so on. The high tide on the high seas is more than an hour earlier than that in the inner harbor.
