The retailers are starting their preparations earlier and
earlier. It seems to be a norm to bring out the decorations in
October, even before autumn and summertime can end (the latter on
the last Sunday of the said month).
And now, according to my friends, Tesco's is selling mince pies in
September! 
Mmm...mince pies...no, they contain no meat, just spices, sugar,
currants and suet.
Back to the topic, it seems that for Christmas and Mooncake
festival, the festivities start early since there are no
commerically-significant holidays ahead, except for Thanksgiving
Day in the USA perhaps. I doubt Hari Raya Puasa and Deepavali mean
a lot to big retail chains stationed here (sad, I know).
