Rhu might be right-- in england, the christian church is the official religion.. but here in US, there is no official religion.. So its not the Advent season, any more than it is the Ramadam season..
our "seasons" are secular.. for most of us, "summer" is defined as the period from Memorial day (May 31st, to Labor day-- this is not the Summer as defined by the position of the sun--(which would move summer to apx. June 21 to Sept 21st)
hunting season depends on where you are, and what your are hunting. same too, with fishing season, and if any one is interested, some where, in some thread, are the open dates for frog hunting in CA!
christmas season in US is commercial season.. and to make it even less christian, its usually Holiday season.. after all, Ramadan requires a fast during daylight hours, and family feasts in the evening.. and sunday is the start of hanukkah and merchants want all of these people to come out and shop too, even if they don't give gifts, they are encouraged to purchase new table where, or candles.
all to often the Christ is taken out of christmas, and all that is left is the chi..happy Xmas and have fun shopping..
in Japan, christmas is also celebrated, usually with small gifts for children, and with a "christmas cake" --every one has christmas cake.. the cake is chocolate, cream filled rolled cake, decorated like a log-- a Buche do Noel-- i think is the french name.. like irish soda bread in US for st Pats.. everyone gets a chrismas cake.. and thats about it... in Japan, christmas is a bakers holiday!
