It would be possible to make an electronic version of this so that the frame slides into the right position, and the current day lights up.
The hard part would be all the cloud based backend stuff so people wouldn’t have to remember to slide the frame at the end of the month and remember how many days are in each month. And vendor lock-in so people don’t attempt to use non-Julian calendars or any equally distasteful things. Calendar as a Service it would be called.
