👉 Subanniversary is a term used in the context of anniversaries, specifically referring to events occurring after the original anniversary. It typically refers to an event that occurred less than one year after the original anniversary date. For example, if someone celebrated their 25th birthday on April 1st and then celebrated their 30th birthday on June 1st, it would be considered a "subanniversary" because it occurred more than one year after the original celebration.
