Sorry for I can only partial read a few lines before eyes go blur.
DOS-clock is usually out of sync with the real-time clock. My old calendar used RTCL I/O read for date&time, INT_0x10 for display and calculated DOW with the help of a few small LUTs (year 1900 based).
The final version replaced INT_10 calls with my own OUT-routines.
And I used a few slow AAM there.

No sign in CLAX. I don't know what could be wrong!  Can you try again?
