As the lunar cycle is about 29.5 days, successive tides are approximately 24/29th of an hour later each day or about 50 minutes but many other observations and considerations are required to develop accurate tide tables. On the Atlantic coast of northwest Europe, the interval between each low and high tide averages about 6 hours and 10 minutes, giving two high tides and two low tides each day, with the highest tides about 2 days after full
Ecclesiastical full moon moon is useful and necessary since the full moon may occur on different dates depending where one is in the world.
