To determine how many days ago September 7th, 2022 was, we need to know the current date. Since I don't have access to real-time information, I can't give you the exact number of days.
However, you can easily calculate this yourself using an online date calculator or by subtracting the number of days from today's date to September 7th, 2022. Many calendar applications and websites offer this functionality. Simply enter both dates and the calculator will provide the difference.
