Here is a composite of ideas from my five science classes.
1. Time Zones. Because the times within a time zone are not the exact sun time for every area, maybe that would change how the photoperiod is figured.
2. A day is not exactly 24 hours, therefore it would not be divided equally into 12 hours.
3. A year is not exactly 365 days. Maybe the extra 1/4 day each year adds a little extra time to the Equinox day.
4. If the speed of the Earth were not constant, maybe it is slower on the Equinox.
5. Because the Earth is revolving at the same time it is rotating, it takes more than 24 hours for the Earth to turn back towards the Sun the following day. This could add extra minutes the the photoperiod.
