The Good Side of the 9 11 Attacks

If I were to point out the good side of the 9 11 terrorist attacks, I would say they had created a easy way to remember how many days there are in each month of the Gregorian Calendar, the calendar we use here in the west. 

Month 2 has 28 days or 29 on a leap year. 

Months 4, 6, 9 and 11 have 30 days the rest of the months have 31 days. 

2 Planes hit the trade towers 

4 Planes were hijacked 

6 Looks like an upsidedown 9

9 is the month of the attack 

11 is the day of the month when the attack happened 

Remember 4, 6, 9 11; April, June September and November (30 days) the rest have 31 except for February.
