This question was asked on a Friday and exactly 11 weeks ago it was also a Friday.
The day eight weeks ago was the same as what day it is today, except eight weeks earlier.
The day of the week 10 weeks ago was the same day of the week that it is today.
49 weeks ago was approximately 11 months and 3 weeks ago from today.
To determine the date that was 42 weeks ago, you can subtract 42 weeks from today's date. Since there are 7 days in a week, 42 weeks equals 294 days. If today is October 2, 2023, then 294 days ago was December 11, 2022.
