Some do, most don't. It always depends on when they're bred that will coincide to when they will calve. Some cows may calve on a New Moon, some may calve when the moon is at it's first or last quarter, or some may calve in between any of these times.
Cows are not plants, they are animals, which are capable of growing in any and all seasons.
