If you are using the sleep command for greater than 1 day and you are also using the "32768 watch crystal" for sleep timing then you might want to re-think your code. My testing reveals, using the DS3231 precision real time clock, 10's of seconds drift everyday! Unless you can keep the ambient temperature on the board within a few degress of the crystal's calibration then the time error is reduced.
Note: In my testing, I have a setback thermostat which reduces the temperature at night time greater than 10-15 degress F.
