"a time, and times and half a time"

I am still stuck in Rev 12 as it looks like there is more to unravel than what I initially thought.

For instance, the phrase "a time, times, and half a time" looks like a symbolic expression used in Daniel and Revelation. It represents a period of time, but the exact duration can be somewhat ambiguous and open to interpretation as far as I am concerned.

For instance, where does the teaching come from that "a time, and times and half a time" equates to 1260 days?

I do understand the calculation when saying that one year = time, but where does it state in Scripture that this is the answer or do we just accept it as this is what we were taught?

Could the "time" and "times" be seasons rather than calculable days?
