Tide occurs on every place after an interval of 12 hours 26 minutes. Earth completes a rotation op. its axis in 24 hrs. In this way, tide should occur on every place after 12 hrs, but it is not like that. The main reason for this difference is that on the completion of one rotation of the earth, the moon also moves on its path.
Moon completes the revolution of the earth in 28 days. In 24 hrs or 1 day, it completes 1/28 part of the circle. That location of the earth takes 52 minutes to come in front of the moon. Thus, on every place, the second tide occurs after an interval of 12 hrs 26 mins.
This situation of the tide can be explained with the help of the following diagram:
