How many neap tides and spring tides are there every month

2 neap tides & 2 spring tides in each lunar month.

Explanation:

Each lunar month has 2 neap tides and 2 spring tides, this is because each lunar month has 1 new-moon and one full-moon phase that results in spring tide whereas after seven days of spring tide the sun, the earth and the moon form a right angle leading to a neap tide.

Spring tides occur as the highest high tides when the sun, the moon and the earth are in the same straight line. Neap tides are the tides when there is lowest difference between the low tides and the high tides of the day.
