Question

Assume that new moon day falls on 27th march. State the likely date on which there would be the full moon day

Answer 1

Answer:

11 th April will be the full moon day because there will be a difference of 15 days between a new moon day and a full moon day

Answer 2

1. The date on which there would be a full moon day after 27th March having a new moon is April 11th.
2. The moon takes  29.18 to about 29.93 days to complete one rotation.
3. There is a range of time period because the moons orbit is not perfectly circular and even the earth's orbit around the Sun is not perfectly circular.
4. This period is known to be synodic month.
5. New moon to full moon is half the cycle thus takes half of the time of synodic month.
6. Thus its  14.59 to about 14.965 days.
