∙ 12y agoThat depends on the year. There are always at least 52 Saturdays and 52 Sundays in a year, so most years there are 104 in total. Some years there can be 53 Sundays and 52 Saturdays, in which case the total is 105. There can also be 52 Sundays and 53 Saturdays, again giving a total of 105. If a leap year starts on a Saturday, then there are 53 Saturdays and 53 Sundays, so there are 106 in total.
there 5 sundays,mondays,saturdays in every 200 years
4 years
More like every 28 years, I think.
Over the very long average, once for every seven years. And it's "often".

every 823 years.
once every 365 years!
The next six years in which that happens are 2014, 2025, 2031, 2036 and 2042.

The odds are exactly 14.5%, which makes the average frequency once per 6.9 years.
There are 14 calendar variations (7 days of the week plus leap years). Some years October will have 5 Fridays, 5 Saturdays, and 5 Sundays. October 1999, 2010, 2021, and 2032 all have 5 Fridays, 5 Saturdays, and 5 Sundays. This looks like an 11 year gap, but October 1988 and 2043 do not have 5 weekends.
There is an internet hoax going around claiming that certain occurrences of five days in a month occur every 823 years. For examples, in October 2010, there were five Fridays, Saturdays, and Sundays. However, this occurrence occurs at the most every 11 years. The next time five Fridays, Saturdays, and Sundays occurs in a month is March 2013. The next time it occurs in October is October 2021.
According to my desktop calendar, July will have five Fridays and Saturdays (and even some Thursdays) in 2016, 2021, 2022, 2027,2032, 2033, etc... If you look at http://www.timeanddate.com/calendar/monthly.html?year=2021&month=7&country=1 you will see that 2021, 2027, 2032 do not have 5 Sundays. The other years 2016, 2022, 2033 do have 5 Fridays, Saturdays, and Sundays. You are little confused since your first parahraph discusses Fridays and Saturdays, in which case 2021 and 2022 do indead have 5 Fridays and 5 Saturdays in July. In paragraph two above, you begin talking about Sundays and which years in which July will 5 each of Fridays, Saturdays and Sundays. Every month with 31 days will have 5 instances of the first 3 days in the month. This will repeat in a 5-6-5-11 year cycle and then repeat. So it should be 2016, 2022, 2033, 2039, 2044, 2050, 2056 - don't forget to consider leap year which will cause a 1 day shift.
