I think it depends on the people and the meaning of the name, etc. I know a Summer
whose bday is in Nov. and Aprils whose bday is not in Apr. April
's meaning isn't limited to the month, so that may be part of it. However, some choose the name because of when the baby's born. Day of the week names sound kind of tacky on people imo. I like Summer
as people names, but Spring
and Fall could sound kinda tacky and Winter
I prefer to leave as a surname.
That said, I think those preferences are specific to English and my opinions of such might vary depending on the language. Using seasonal kanji for names is pretty standard in Jpns., so even spring can work quite nicely and often has something else attached.Haru
All of those could use the kanji for spring.
The kanji for winter (fuyu) is not so common in modern names, so Fuyuko would seem kinda dated and I'd be expecting an old lady if I heard the name.
Natsu (summer) and Aki
(autumn) also can work nicely in a number of names.
The month names are just numbered in modern times, so that could be a little boring, but I believe there were once actual names for the months, and kanji taken from the mo. of Mar. is sometimes used in names still.
As for days of the week, they're taken from the names of planets w/ yobi put on the end instead of the character for planet. I met a guy named Mokusei after the planet who had a brother named Mokkin (xyolophone)... Yes, these are as random as names here as they would be in the west. When their parents had another baby, the older 2 babies begged their parents to give their brother a more normal name. Yuu
really owes them for that one.
