September 1st is Wednesday. What else can I do for you

There are four Wednesdays and four Saturdays in July of a certain year. What day is July 1 of that year?

Sunday!
Because July is 31 days, 31 divided by 7 equals 4 and 3
Then there must be five in three weeks. Based on four Wednesdays and four Saturdays, we can get five Sundays, Mondays and Tuesdays
So, only one day is Sunday can the equation hold~

There are four Wednesdays and four Saturdays in March of a year. What day is the 7th of this month?

March in any year of the Gregorian calendar is 31 days. On the 1st, 2nd and 3rd of March, their weekly values are all 5 in the current month. On the 4th, 5th, 6th and 7th, their weekly values are all 4. Therefore, the 4th should be Wednesday, and the 7th of the current month should be 7-4 + 3, which is Saturday
