This will occur in any month that has 31 days when the 1st falls on a Friday. In any given year, on average, one month having 31 days will start on a Friday since there is a 1:7 "chance" of a month starting on any given day of the week, and there are seven months that have 31 days in them. Simply check out the calendars for 2 or 3 years and you will find that this is a fairly common occurance.
More like every 28 years, I think.
There is no special name for that. Note that this can't happen for June - June only has 30 days. For months with 31 days, this is fairly common; on average, one in every seven years has (for example) a July with these properties.
This happens on average of once every 7 years- 4 times in every 28-year cycle of the calendar. It happens whenever March first is a Friday..
Every year.
there 5 sundays,mondays,saturdays in every 200 years
Every year has more than 5 Fridays, 5 Saturdays and 5 Sundays.
every 823 years.
once every 365 years!
Every time February 1st falls on a Monday !
Nothing. There are 5 Fridays, Saturdays and Sundays in October about once every seven years, not 823.Nothing. There was a claim that 5 Fridays, 5 Saturdays and 5 Sundays in October happens only every 823 years, but this is not true. It happened in 1999, 2004, 2010 and the next occurrence will be in 2021.

The claim is that every 823 years, there is a month with 5 Fridays, 5 Saturdays, and 5 Sundays. It happens in October 2010. But this is an internet hoax. October previously had 5 Fridays, 5 Saturdays and 5 Sundays in 1982, 1993, 1999 and 2004, and it will happen again in 2021. In fact, to my knowledge, there is NO calendar event [which is what this category pertains to] that regularly happens every 823 years. The Western world switched from the Julian to the Gregorian calendar more recently than that! (in 1582)
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.
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.
People ask this same question? No. seriously - some months have 5 Fridays, Saturdays and Sundays. August 2010 - July 2011 etc.
There is no special name for that. Note that this can't happen for June - June only has 30 days. For months with 31 days, this is fairly common; on average, one in every seven years has (for example) a July with these properties.
