Day-Of-Week can cause bug in DST calculation #17

Closed gaborsimon closed 7 years ago

gaborsimon commented 7 years ago

Sakamoto's original algorithm calculates the Sunday as number 0. Currently the code performs re-numbering to number 7 before the DST calculation. This can cause problem.

The Sunday has to remain the number 0 and the RTC has to use this value to draw the "SU" onto the LCD.
