How often do spring and neap tides occur

Without thought to the season, Spring tides happen [two times] every [lunar] month the whole year. When the Sun and the Moon are quadratic, Neap tides also happen two times during a month.

Here is a picture to help show you:

(With the Spring tide, the moon is toward the "left" or "right" of the Earth. With the Neap tide, the moon is "above" or "below/under" the Earth. It's kind of hard to explain).

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
