A lunar day is a considerable measure longer than a day on Earth, as indicated by another NASA video. We measure days from twelve to twelve or dusk to nightfall.
On Earth, a day takes 24 hours, however it will change by an up to 29 seconds as a result of the erraticism of Earth’s circle. On the moon, a day is 708.7 hours, or 29.53 Earth days. On Oct. 16, the test hit the 100 lunar-day check.

Since the Earth moves around the sun in a generally roundabout circle, when one pivot is done the sun will show up somewhat west of its position in the sky in the meantime the day preceding.
The Earth likewise wobbles a bit, which modifies the length of a day by a little sum.
A comparative thing happens to the moon. The 100 days LRO passed are mean sunlight based days — a normal.
The length of a day on the moon can change, being 6 hours shorter or up to 7 hours longer than the mean of 28.53 Earth days, for similar reasons that the Earth’s day can shift, in addition to one other: The moon’s circle isn’t an impeccable circle.
The moon additionally wobbles a bit from side to side (a marvel called libration), so from Earth a fragment of the far side is occasionally noticeable.
