What are major iOS sales events?

[FlowStudioGames]

Hey guys, I have created a list of major iOS sales events and holidays. It would be great if you can add some more even for other countries except of the US as I have done now.

Here is Google Docs open document which all of you can edit and benefit from: http://bit.ly/iOSsalesEvents

And what I have found so far in a short form:
1. 1. - New Year Day
14. 2. - Valentine´s Day
Third Monday in February - President´s Day
Saturday to Monday, from March to May - Easter
Last Monday in May - Memorial Day
4. 7. - Independence Day
Beginning of September - Back to school
Last Monday in September - Labour Day
31.10. - Halloween
Fourth Thursday in November - Thanksgiving Day
The day after Thanksgiving - The Black Friday sales
Monday following Black Friday / Thanksgiving - Cyber Monday
25. 12. - Christmas

Thanks for collaboration!
