According to an email I just received, when you add the year in which you were born and the age you are now or will be by the end of this year the total comes to 2018 EG: someone I know will be 71 on the 22nd and was born in 1947....Hence: 71 + 1947=2018 : another is 42 (March birthday) and born in 1976....Hence: 42 + 1976=2018 : me, am going to be 74 on the 14th and was born in 1944....Hence: 74 + 1944 = 2018??? According to the email, this will happen again in 1000 years ??? Is there a simple explanation for this???.....clm or pnm or any other user......please explain......thank you

Is there a simple explanation for this???.....clm or pnm or any other user......please explain......thank you Obviously, generally, if you add to the year you was born, your actual age, the result must be 2018, the actual year, i.e., 1944 + 74 = 2018. Someone born in 1975 is now 43 years old (if born in a date from Jan 01 to Oct 12 in which case "already" is 43 years old) so 43 + 1975 or, alternately, 1975 + 43 = 2018. The operation is conmutative what tends to confuse. The only problem to consider is the birth date with respect to the moment you are considering the sum, for instance, a person born on Jan 01, 1980 is actually 38 years old thus 1980 + 38 = 2018 but a person born on Dec 31, 1980 is "still" 37 years old (until Dec 31 that person will not have 38), in this case, 1980 + 37 = 2017 and the rule fails . But all this has no relation at all to a 1,000 years cycle (the only cycle with dates in the gregorian calendar is 400 years due to leap years as you know), this is a simple invention, very frequent in these type of mails.

Thank you, clm. In other words, this is not soley unique to 2018.......as it will work in 2019 as I will be 75 then and year of birth has not changed so total of birth year and age (75) in 2019 will add up to 2019....... should have seen that but email sounded convincing that 2018 year was unique when in fact it is not!!

I'm pretty sure this is one of those email hoaxes that goes around year after year, In 1000 years time though it'll be 3018 not 2018 again. If you add your birth year to your age you turn that year you get the current year everytime year on year :)
