Passed vs. Past
Passed is the past tense and past participle of the verb pass. Past is usually a preposition, adverb, adjective, or noun referring to an earlier time or a position beyond a point. The forms overlap in sound for many speakers but have different grammatical jobs.
Use passed when you need the past form of the verb pass: “She passed the shop.” Use past for meanings such as beyond or earlier: “She walked past the shop” and “in the past.”

Quick tests
Meaning / construction test
Does the sentence require the past tense or past participle of the verb “pass”?
If yes: Use “passed.”
If no: If the meaning is beyond, earlier, or a previous time/period, use “past” in the grammatical role the sentence requires.
Caveat: “Past” can be a preposition, adverb, adjective, or noun, while “passed” is a verb form. Identify the grammatical job as well as the meaning rather than choosing by sound.
