Ways to tell them apart:

• As time passed emphasizes the passive passage of time, much like watching the hands of a clock move without interference.
• As time progressed suggests a more active or purposeful movement through time, perhaps towards a future goal or change.
• Both expressions mark the transition of time, but passed can feel more neutral, whereas progressed implies advancement or development.
• Consider your goal: if the situation matures or evolves, progressed might be apt; if it simply continues over time, you might choose passed.
• Remember: passed is often used when the passage of time is viewed in hindsight, while progressed may imply ongoing development.
