Which consequence arises from approximation errors within programmable astronomical mechanical calendars?

💡 Explanation

Calendar drift appears when using a limited variable set to approximate non-repeating astronomical cycles. The approximation introduces rounding errors with each calculated interval, therefore cyclical functions desynchronize because the discrete digital approximation shifts rather than calculating to infinite precision.
