Question

Define new moon and spam are not ballowed​

Answer 1

Answer:

In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude.[2] At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. Daylight outshines the earthlight that dimly illuminates the new moon. The actual phase is usually a very thin crescent.[note 2]

The original meaning of the term new moon, which is still sometimes used in non-astronomical contexts, is the first visible crescent of the Moon after conjunction with the Sun.[3] This thin waxing crescent is briefly and faintly visible as the Moon gets lower in the westerly sky after sunset.

A lunation, or synodic month, is the average time from one new moon to the next. In the J2000.0 epoch, the average length of a lunation is 29.530588 days (or 29 days, 12 hours, 44 minutes, and 2.8 seconds). However, the length of any one synodic month can vary from 29.26 to 29.80 days due to the perturbing effects of the Sun's gravity on the Moon's eccentric orbit.[4] In a lunar calendar, each month corresponds to one lunation. Each lunar cycle can be assigned a unique lunation number to identify it.
