It's all up to you. [See related question] A solar year is based on the Earths orbit around the Sun, whereas a lunar year is based on the cycle of the Moon. Mainly used now in Islamic calender's.
The landing stage was left behind as it was not needed, but more importantly, the lunar module needed to be as light as possible to ensure it could be blasted from the surface with the restricted amount of fuel available.
Lunar eclipses always happen at the full moon phase. A lunar eclipse happens when the Moon is DIRECTLY lined up with the Sun and the Earth, so precisely that the Earth's shadow hits the Moon.
Islam uses the lunar calender instead of the solar calendar. The phases of the moon just show the date. This is used to determine things like eid, Ramadan laylatul-qadr.

Wesak Day is on the 15th day (full moon) of the 4th Lunar Month. In the Lunar calender there is a possiblility of leap month (just like a leap year in the universal calender, i.e. every 4 years). However the leap month of a Lunar calender is determined by an almaniac (not every four or every two years basis). In such circumstances there is a possiblity of having double 2nd Lunar month or a double 4th lunar month and so on. So if there is a double 4th lunar month, then Wesak will be internationally accepted on the 4th lunar month on the 15th day (full moon) in the month of May of the universal calender and in most cases on the first 4th lunar month.
Basically, only when calculating the day of "Easter".

The Julian Calender (which became the Christian Calender with only a few holidays retained) is a solar calender, based on earth's orbit of the sun. Previously the Romans used a lunar calender like the Chinese, based on the moon's orbit of the earth. The solar calender was more efficient, and Julius Caeser was a man who liked efficiency, so he pushed for adoption of the calender which bears his name.
