Semi diurnal tides occur twice a day (2 low tides, 2 high tides) and diurnal tides occur once (1 high tide one low tide) per day.
there are 732 tides a year! That is about right. But, it depends if it is diurnal, twice a day so 365 x 2 = 730, minus 2 in leap years, 728. if tide is semi-diurnal, then there are 4 tides a day 1,460, and it can be mixed with 3 tides a day.
they are what you call when there are two tide cycles in one day--when there is only one tide cycle in one day that is called diurnal--diurnal tides occur in the Gulf of Mexico.

Generally, but not always, there are 2 low tides and 2 high tides that occur each day. This is determined in large part by the the Moon's gravitational pull.

Diurnal, Semi-diurnal and Mixed
Mixed Semi-Diurnal
The three main tidal patterns are Diurnal, Semi-diurnal, and Mixed Semi-diurnal. If an area has one high tide and one low tide each day it is called Diurnal. If the area has two high tides and two low tides of the same height , it is called Semi-diurnal, if the tides are differing heights it is called mixed Semi-diurnal.

Two different ways to classify times are the Diurnal Tide and the Semi-diurnal Tide. A diurnal tide has one episode of high water and one episode of low water each day. A semi-diurnal tide has two episodes of equal high water and two episodes of low equal water each day. They are both also classified as astronomical tides, meaning they are influenced by gravitational actions of the sun, moon and Earth.

semidiurnal tides are when there are two tide cycles in one day, and that is the common tides. diurnal tides are when there is only one tide cycle in one day, like in the Gulf of Mexico.
hey i think its because of the solar system
