Queueing theory

__NOTOC__ Punctuality is the characteristic of completing a required task or fulfilling an obligation before or at a previously designated time based on job requirements and or daily operations. "Punctual" is often used synonymously with "on time". An opposite characteristic is tardiness, or more colloquially "being late".
