1. Literally, to walk past (someone or something) in a unified group or regimented file or formation. We all trembled in fear as the soldiers marched past. As if to add insult to injury at having to stay home and study, a huge crowd of people all marched past my window on their way to the ceremony.

2. To proceed or progress onward toward the future without one. My greatest fear is being stuck in some dead-end job, watching the days of my life march past. They deserve the disqualification—let the championship march past them this year!
