Dondaihe Tide Table Query Year

The rise and fall of sea water during the day is called "tide", and when it occurs at night it is called "tide", so it is collectively called "tide". Ancient Chinese books say that the water of the sea becomes tide when it rises in the morning and tide when it rises in the evening. Its occurrence is related to the sun and moon, and also corresponds to our country's traditional lunar calendar.

On the first and fifteenth day of each lunar month, the tide level reaches its highest at 6:00 am and 18:00 pm, and reaches its lowest at 12:00 noon and 0:00 am. Then the daily high and low tide times will be postponed by 48 minutes.

The rise and fall of sea water in Dongdaihe River

There are two high tides every day, 12 hours apart. The high tide usually lasts for more than an hour before ebbing, and the lowest tide is in the middle of the two high tides.

The high tide time is different every day and rotates once every 15 days. Therefore, the next day's high tide is delayed by 0.8 hours (48 minutes) from the previous day's high tide time. The daily high tide time can be calculated based on the lunar calendar date. The calculation formula is as follows:

From the 1st to the 15th day of the lunar calendar: high tide time = date * 0.8

From the 16th to the 30th day of the lunar calendar: the high tide time = (date - 15*0.8

Notes: Everyone needs to pay attention to safety. Don't go near the seaside when the tide comes. This is very dangerous. Adults should pay attention to the movements of their children and stay away from the sea.
