Proof in cold print: July 2011 and July 2834 are not even the same.
Repeating CalendarsThe next time that the 2011 calendar repeats itself is in the year 2022, which is only 11 years later. What's more, a calendar month that contains 5 Fridays, 5 Saturdays and 5 Sundays occurs nearly every year: Both July 2011 and March 2013 have 5 Fridays, Saturdays and Sundays. The next July with same days as July 2011 is July 2016. It does not repeat after 823 years at allEven the claim that the year 2834 has the same calendar as the year 2011 is false (see picture).For instance, July 2011 has 5 Fridays, Saturdays and Sundays. 823 years later, July 2834 has 5 Saturdays, Sundays and Mondays. That is a 5th Monday instead of a 5th Friday.
Variations of the urban myth:In a common/regular year, January and October look the same. In a leap year, January and July look the same.

To calculate the total number of days in 2 years and 9 months, we first convert the years to days. There are 365 days in a year, so 2 years would be 2 x 365 = 730 days. For the 9 months, we need to consider the varying number of days in each month, which totals to 273 days (9 months x 30 days). Adding the days from the years and months together, we get a total of 730 days + 273 days = 1003 days in 2 years and 9 months.
