To find the date 17 weeks ago from today, you would subtract 119 days (since 17 weeks = 17 x 7 days) from today's date. If today is October 24, 2023, then 17 weeks ago would be June 27, 2023.
There are 7 days in a week. If you divide 492 by 7, there is a remainder of 2. You can then use the 2 to go back 2 days, so the answer is Monday.
To find the date 35 weeks ago, you would subtract 245 days (since 35 weeks x 7 days/week = 245 days) from today's date. If today is October 18, 2023, then 35 weeks ago would be January 3, 2023.
To find the date that was 103 weeks ago from today, you would subtract 103 weeks from today's date. Since there are 7 days in a week, 103 weeks is equivalent to 721 days. If today is October 18, 2023, then 721 days prior would be around October 18, 2021.
