Which day of the week is the best? It's really quite obvious, but here's the official list:
1. Friday
2. Thursday
3. Saturday
4. Sunday
5. Wednesday
6. Tuesday
7. Monday
Friday is clearly the best choice for number 1. Friday has been a popular day since the days of elementary school and sleepovers. Thursday is probably the most surprising, having jumped ahead of the very popular Saturday, but Saturday night signals that the weekend is already half over, a very depressing thought, whereas Thursday night means the weekend is just about to start.
The rest should seem obvious.
