Amazon Prime Day 2025 took place from Tuesday, July 8, through Friday, July 11. This four-day event was the longest Prime Day to date, lasting 96 hours and offering exclusive deals to Amazon Prime members. The sales started at midnight Pacific Time on July 8 and ended at 11:59 p.m. Pacific Time on July 11.

If you were referring to a specific Amazon Prime Day on the 20th of a month in 2025, there appears to be no Prime Day event on July 20. The official Prime Day in 2025 was held earlier in July, not in late July or August. For context, in 2024, Amazon held a Prime Day event on July 20-21 in India, but this differs from the global 2025 date.
