Any year, like 2011, where July 1 falls on a Friday. Such years coming up are 2016, 2022 and 2029. Years in the recent past include 2005 and 1994.
actually 2005 had 5 Fridays Saturdays and Sundays in July
More like every 28 years, I think.
Never.
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.
In any given year, July can have 5 Fridays, 5 Saturdays, and 5 Sundays if the month starts on a Friday. This occurs in years when July 1 falls on a Friday, meaning the month will have the dates 1, 8, 15, 22, and 29 as Fridays, 2, 9, 16, 23, and 30 as Saturdays, and 3, 10, 17, 24, and 31 as Sundays. This alignment happens roughly every 28 years.
2011 2016 2022 2033 2039
This happens in any 31-day month starting on Friday (such as July 2005).
July 2022 has five Fridays. The Fridays in July 2022 fall on the 1st, 8th, 15th, 22nd, and 29th.
People ask this same question? No. seriously - some months have 5 Fridays, Saturdays and Sundays. August 2010 - July 2011 etc.
Exactly 14.25% of all July 23rds are Wednesdays. 14% are Sundays, 14.5% are Mondays, 14.25% are Tuesdays, 14.25% are Wednesdays, 14.5% are Thursdays, 14% are Fridays, and 14.5% are Saturdays.
October had 5 Fridays and Saturdays and Sundays in the year 2010 and will have it again in 2021 than 2027, 2032, 2038 , all the months with 31 days in them have the same pattern 11 years than 6 years than 5 years than 6years than 11 than 6 than 5 than 6 doesn't matter where you start at 5 or 6 or 11 just do 4 in a row and it will add up to 28 years October has 5 Fridays, Saturdays and Sundays. 5 times starting in 2010 , 2021, 2027,2032 and 2038 December will have them in 2017,2023,2028,2034 and 2045 January is 2010, 2016,2021,2027 and 2038 march is 2013,2019,2024,2030,2041 may is 2015,2020,2026,2037 and 2043 and the last month with 31 days in it, July has them on 2011,2016,2022,2033,and2039
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.
