Five Sundays, five Mondays, and five Tuesdays in one month. People believe that this happens once every 823 years. What if this was all a myth?

People get way too excited for this once in 823-year event when this occurs at least once a year or more. This is occurring in October and December of 2017.

The calendar 823 years into the future  is not even the same as the calendar in the past. For example, August 2014 had five Fridays, five Saturdays, and five Sundays. 823 years later in August 2837 it will have five Fridays, five Saturdays, and five Sundays.

7 months out of the year have 31 days. Each of the seven months will have three weekdays that will be repeated five times. So, any 31-day month that begins on Friday will have five Fridays, five Saturdays, and five Sundays. For instance, August 2014 had five Fridays, five Saturdays, and five Sundays. October 2014 had five Wednesdays, five Thursdays, and five Fridays.

It does not take a rocket scientist to know that this fact is a myth. There are seven different days that this could start on. Therefore, there are only seven possible days for the year to start on. Without the leap year, there are only seven possible calendars.

This will occur in the months of January, March, May, July, August, October, and December. This event will occur in this month with five Sundays, five Mondays, and five Tuesdays.
