Hathanksmas 

The combination of Halloween, Thanksgiving and Christmas into one holiday. This is generally most obvious in large stores in the US where you can find all three holiday's decorations in the same isle a month before the first one has even occured.

Happy Hathanksmas! Let's put on some costumes so we can go sing carols while the turkey cooks.

Halthanksmas 

A holiday beginning on October 31st and spanning through to December 31st, created to facilitate the retail season;
A season completely devoid of any spiritual, social or religious significance, devoted solely to bolstering the sales of National mega-chains;
A new opportunity for Hallmark Cards to create a non holiday

"Don, have you started your Halthanksmas shopping? Its getting late - yesterday was Labor Day!"
"Last year my parents really missed the boat on the Halthanksmas shopping sales, and the new Nintendo DS add on were all sold out by October- I'm so pissed",
"I can't believe I forgot to get Doreen a Halthanksmas card ,and gift certificate to Wal-Marts- I'm such a shitty boss...."
