Easily figure out what day of the week any date falls on for this year, last year, or next year by using the Magic Day and a Key Date for each month. Take a couple minutes and learn this fun math trick with your kids. This is easy and incredibly handy for the rest of your life.
It is now 2014. Fourteen starts with an F, so you can remember the MAGIC DAY is FRIDAY. This means that easy to remember dates of each month fall on Friday. All these dates fell on Thursday last year (the memory trick is that 13 starts with Th) and will fall on Saturday in 2015 (Thursday-Friday-Saturday). What are the KEY DATES each year?
Double Dates fall on the Magic Day of Friday. Even Double Dates are 4/4, 6/6, 8/8, 10/10 and 12/12 (April 4th, June 6th, August 8th, October 10th, and Dec 12th) and all are Fridays this year. Some fun math will quickly tell you what day any date falls on during these months.
February: Start with February, which has 28 days all three years. All the Sevens (7th-14th-21th-28th) in February are on the Magic Day which is Friday for 2014. Notice that Valentine’s Day always falls on the Magic Day. It is easy then to figure out what day any other date falls on. For example, Feb 9th would be 2 days after Feb 7th, and would be on a Sunday.
March: The last day of Feb (the 28th) is a Friday so March 1st is a Saturday. Now see that in March, all the Sevens (7th-14th-21th-28th) are also on the Magic Day which is Friday for 2014. Again you can easily figure out which day of the week any date falls on.
January is easy if you picture February with 2/7 on a Friday, a week earlier 1/31 was on a Friday and so 1/3, 1/10, 1/17, and 1/24 are also on Friday.
July: Celebrate the 4th of July (7/4) because it is always on a Magic Day, this year Friday.
November, May and September: Here is a simple memory reminder, “A friend works at the 7/11 from 9 to 5.” Those pairs of numbers are reversible (7/11, 11/7, 9/5 and 5/9) and all fall on Friday.
