Never.
October 2011, December 2012, March 2014 for starters. In other words, how often does a 31-day month begin on a Saturday? Fairly often.
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
To determine who travels more miles per day, we need to calculate the average daily distance traveled by each person. William travels only on Saturdays and Sundays, which means he has a total of 8 days (4 Saturdays and 4 Sundays) to travel 400 miles, averaging 50 miles per day. Jason travels every weekday, totaling 20 days in a month, and has flown 500 miles, averaging 25 miles per day. Therefore, William travels more miles per day than Jason.
Well, isn't that a delightful question! In a typical year, there are usually four months that have 5 Fridays. However, in a leap year, one extra month may also have 5 Fridays. It's like finding a hidden treasure in the calendar!
You would get two or three checks a month, depending on how many Fridays in that month. You would get 26 checks per year most years and sometimes get 27.

2021, 2027, 2032, 2038, 2049, etc.
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.
This happens in any 31-day month starting on Friday (such as July 2005).
