If by "between" you mean "between but not including", then the answer is 9999 - 999 - 1 = 8999.If on the other hand, you mean to include both 9999 and 999, then the answer is 9999 - 999 + 1 = 9001.
Not sure about the exact number but it is approx 1086.

Well, honey, the even integers between 1000 and 9999 can be found by dividing the total range by 2, since every other number is even. So, 9999 - 1000 = 8999, and 8999 divided by 2 gives you 4499 even integers. But remember, I'm not your calculator, so don't come crying to me if you can't count 'em all yourself!

If by "between" you mean "between but not including", then the answer is 9999 - 999 - 1 = 8999.If on the other hand, you mean to include both 9999 and 999, then the answer is 9999 - 999 + 1 = 9001.
Infinitely many. There are, in fact, infinitely many numbers between any two numbers.
WHOLE NUMBERS...The numbers (integers or whole numbers) between two numbers would not include the two numbers, so 9999 - 2 = 9997. Subtract 2 for the numbers 0001 and 9999.Another AnswerThe answer is infinity. If you ask unqualified questions, expect infinite answers.
In base ten, there are 9000 four digit number, the numbers are from 1000 to 9999. If you allow leading zeros, then there are 10000 numbers. [0000 - 9999]

10,000. from 0000 to 9999.
There are 3168 such numbers.

If you count 0000 to 9999 you have 10,000. For whole numbers you have 9999. * * * * * Not sure about "whole" numbers. There are 10,000 in all, of which 9000 (from 1000 to 9999) do not have leading 0s.
To be palindromic, the year must be of the form XYYX where X and Y are digits, so we need only consider the first half of the number, namely the XY and the question becomes how many numbers XY are there between 20 and 99 such that XYYX is between 2000 and 9999.The answer depends upon the definition of "between":If "between" means strictly between, that is the year cannot be 2000 or 9999XY = 20 ⇒ 2002 > 2000 so allowed XY = 99 ⇒ 9999 = 9999 so not allowed⇒ number of years is 99 - 20 = 79If "between" means between but also including the limits, that is the year could be 2000 or 9999XY = 20 ⇒ 2002 > 2000 so allowed XY = 99 ⇒ 9999 = 9999 so still allowed⇒ number of years is 99 - 20 + 1 = 80
