What is the "lunar day"?

In hindu festival notes I have seen things like this -

13 days after the lunar day - or 10 days after the lunar day .. does this mean

13 days after the FULL MOON?

eg. So does this mean that Maha Sivarathri day will be 13 days from the full moon of February (march 2nd)

In counting this - do you count the full moon day as 1 - or the day after the full moon as 1st?

In other words, is it always after 15 days of the full moon that you get the day without the moon?

and on the 16th day, the moon starts showing again?

    It's like labor day but it celebrates the insane.

  • In space exploration, a lunar day is the period of time it takes for the Earth's moon (the Moon) to complete one full rotation on its axis with respect to the Sun. Equivalently, it is the time it takes the Moon to make one complete orbit around the Earth and come back to the same phase. It is marked from a New Moon to the next New Moon.

    With respect to the stars, the Moon takes 27 days 7 hours 43.2 minutes to go around in its orbit; but since the Earth-Moon system has advanced around the Sun in the meantime, the Moon must keep going a while longer to get back to the same phase. On average, this synodic period is 29 days, 12 hours, 44 minutes and 3 seconds long. This is an average figure, since the speed of the Earth-Moon system around the Sun varies slightly over a year, due to the eccentricity of the orbit; the Moon's own orbit also undergoes a number of periodic variations about its mean value because of the gravitational perturbations of the Sun.

    Lunar day is based on the revolution of moon around the earth
