Yabu - there it's lots to love at this time of year if you look hard enough for it.
Chinese new year - a great excuse to let of a Chinese lantern with the kids and eat scrummy chinese food without feeling guilty. Fortune cookies are rather nice as well!
Lots of choccies and drink still left over from xmas that really "need" using up
An excuse to have a good clearout to make way for all the new things at xmas - I always do my "spring cleaning" in January
Being able to make social arrangements easily again - try inviting people over for drinks in December and it is nigh on impossible to find a night when everyone is available. In Jan everyone is skint therefore everyone is available for drinks and nibbles.
Feb is a short month, so payday comes around more quickly (ok, so do monthly bills but this is a positive thread so we'll ignore that bit 
It is a great time to visit the coast as it will be deserted. What beats a bracing walk along the seafront? Just make sure you dress up warm.
Valentimes day - ok it is very commercialised and DH and i don't buy each other stuff but it's nice to make pink peppermint creams with the kids and get them doing crafts for the people they love (we make the net wider and they make cards for friends and family as they're too young for gf's and bf's.
Finally......it's better than the alternative, ie not being alive to enjoy these months.
I am high on life today.....but in an hour I'll be doing the school run in the rain and will probably be hating on January as well by then!!
