3 times, at 0,180 & 360 degrees Is it not twice? (two times?) The third 360 degrees is the start of the next cycle? or the first 0 degrees was the end of the previous cycle?

One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
0 to 360 a complete circle is one cycle
Phase difference is 120 degrees because that is one third of 360 degrees. In a multi phase power system, you want each phase to divide a full cycle evenly. So, in a three phase system, each phase is delayed by one third of a cycle. A full cycle at 60 Hz is 16.7 mS, or 360 degrees. One third of that is 5.6 mS, or 120 degrees. A full cycle at 50 Hz is 20 mS, or 360 degrees. One third of that is 6.7 mS, or 120 degrees.
