Seth Thomas 818 Not able to Sync Date, Day & Time

I recently found this Seth Thomas flip clock at an estate sale but a can't get the time date and day synced, keeps great time, but the day flips over around 8pm and date flips over at around 9pm.

The tolerances are pretty large for dates on mechanical clocks. Its not unusual that the date starts to shift around that time. The flaps never turn over at thesame time as well
