This number is unique in that it lets you recall the days of the week for any day in 2008. Commit the number above to memory, and you can impress your friends with your impressive logical memory! Knowing this magic number will let you instantly recall the day of the week for any day this year in 2008.
To explain: each number in the sequence above corresponds to the first day of the month. The first digit relates to January, the second to February and so on. The last digit corresponds to December. For example, the 11th digit is a 6, and therefore matches up to November. 6 refers to the 6th day of the week – Saturday. Therefore, from this mnemonic, the 1st of November in 2008 is a Saturday. With the same logic, the following dates are also a Saturday:
1 Nov
8 Nov (+7)
15 Nov (+14)
22 Nov (+21)
29 Nov (+28)
The numbers in-between these dates can then readily be calculated on-the-fly. So remember the numbers 8,15,22,29 too! As an example, the 5th November needs to have 4 days added. Count forwards from Saturday: Sunday (+1), Monday (+2), Tuesday (+3), Wednesday (+4). So the 5th November 2008 is a Wednesday.
More examples:
J = January, 1st Jan = 2 (first digit in sequence) = Tuesday
F= February, 1st Feb = 5 (second digit in sequence) = Friday
M = March, 30th Mar = 6 (11th digit in sequence) = Saturday + 1 = Sunday
