Best Time to Book Flights

According to a magazine that I subscribe to - the only one BTW, the best times to book flights are:

Late on Wednesdays and Saturdays. People at work start searching online on Tuesdays but have to wait until they go home and check with family before booking that evening.
Early in the morning or late at night.
After the 7th of the month as people often wait for payday.
6 months in advance.When booking for peak periods do the opposite of most people and book your Christmas flights in summer and in November book your summer trip.
Tuesday and Wednesday flights are cheaper because business travel peaks on Mondays and Fridays.
The same applies to flights that depart at mid-day.
