The day Tuesday comes after Monday. The day Tuesday comes after Monday.
Wednesday comes after Tuesday and before Thursday in a standard week. It is the midpoint of the week, often referred to as "hump day."
This kind of problem is easier to solve if you assign arbitrary dates to what you are trying to figure out. For example, let's say that "Wednesday" was the 12th of December. We will start at the end of this problem and work backwards."The day that comes three days before Wednesday" would be the 9th, a Sunday."The day that comes two days after" this date would be the 11th, a Tuesday."The day that comes two days after" this date would be the 14th, a Thursday."Three days before" this date is the 11th, a Tuesday.
If todays is Tuesday - The day after the day before today is trouble.
The day that comes between Monday and Tuesday is, in fact, Tuesday. However, if you're considering the context of a week, Monday is followed directly by Tuesday without any intervening days. Thus, there is no day that specifically comes between them.
If the day after the day before yesterday was Tuesday, then yesterday was Tuesday, making today Wednesday. Given that the day before the day after tomorrow is Thursday, it confirms that today is indeed Wednesday. Therefore, today is Wednesday.
The day that comes after Friday and before Saturday, while not being sooner than Tuesday, is Friday itself. This is a bit of a trick question, as it implies a time frame without changing days. Thus, the answer is simply Friday.
