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.”
