Some theories call time the 4th dimension. But others say that there is a 4th space dimension. 3 dimensions are up-down, right-left, and forward-backward, and the 4th dimension would be a direction that is perpendicular to all three of those. We cannot perceive it, it would have to be outside the universe as we know it, but it can be described mathematically. And some theories have even more dimensions. I think string theory has 12!

"There are three conventional spatial dimensions: length (or depth), width, and height, often expressed as x, y and z. ...The fourth dimension is often identified with time, and as such is used to explain space-time in Einstein's theories of special relativity and general relativity. When a reference is used to four-dimensional co-ordinates, it is likely that what is referred to is the three spatial dimensions plus a time-line. "
The three dimensions plus time can describe any point at any point in time (corner of State and Congress, 10 feet up, at 4:30 PM EDT)

there a three spatial dimension and time is the fourth. according to superstring and M-theory there are about 7 or 8 more curled up dimension as well.

There are 3 spacial dimensions and the fourth dimension is time itself.

I'm not sure what the fifth dimension is, but the fourth one is time.

There are four dimensions:
three of space, one of time; no-one labels them.
