How can I make an average of dates in MySQL?

Question

How can I make an average between dates in MySQL? I am more interested in the time values, hours and minutes.

On a table with:

| date_one   | datetime          


        

Answer 1

SELECT date_one + (date_two - date_one) / 2 AS average_date
FROM thetable
WHERE whatever

You can't sum dates, but you can subtract them and get a time interval that you can halve and add back to the first date.
