In American English, both "on weekends" and "on the weekends" are used, but there's a slight difference in nuance: ✅ "On weekends" → More general, referring to weekends in a habitual sense. 👉 "I usually go hiking on weekends." (Means you do this regularly on Saturdays and Sundays.) ✅ "On the weekends" → Slightly more specific, often implying contrast with weekdays. 👉 "I work during the week, but on the weekends, I relax." (Emphasizing the difference between weekdays and weekends.) Both are correct, and many Americans use them interchangeably. 😊
