  • I used this process to work it out I have take the ....7th August 2011 (Sunday)

    That means: 11+2+7+3+6 rigth ??? Which is 29...29/7 =4.142857........and now ???

    please Help mee !

  • @TheSylar202 Instead of using decimals, use fractions. 29/7=4+1/7. The 1/7th is all you you need. Because the numerator is 1, the day is Sunday. Hope this helps

  • @TAGSmagic  Why do you calculate 4+1/7 ?? is 1/7 a fraction ?

  • @TheSylar202 1/7 is a fraction but 1 is the remainder. 29 doesn't divide evenly by 7 but 28 does. So when you divide 29 by 7 you get 4 with 1/7 left over. The one is what you use to figure out the day of the week

see all

  • @snookerallan june 12 1722

    12+22+5+5+4=48

    48/7 =6 remainder 6

    6 is friday

  • How about 12 of june1722?

  • is this maths or magic

  • @5Element4 122/7 = 17 remainder 3

    17*7 = 119 122-119=3

    you want the remainder not to divide the answer by 7 again.

  • @gamurx the only reason it doesnt work is user error. the formula works.

  • Doesn't work...
