173 weeks ago from today was 11 Jan 2021, a Monday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 173 weeks from now will bring us back to pre 2023 and we’ll need to factor this into our subtraction because it will change the calendar and fiscal years. For larger calculations like this, I start by subtracting total days, then counting backwards 1211 days on a calendar until getting my solution of Monday January 11, 2021.

How we calculated 173 weeks before today

All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 173 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 06 May, then set the calculation - 173 weeks, and factored in the year 2024
Noted your current time of year: 173 weeks in May will bring us back to April or further.
Counted backwards weeks from current day: date - 06 May, factoring in the 6 days left in May to calculate Monday January 11, 2021
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for January 11

Ways to calculate 173 weeks ago

Calculate it: Start with a time ago calculator. 173 weeks is easiest solved on a calculator. For ours, we've already factored in the 6 days in May + all number of days in each month and the number of days in . Simply add your weeks and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
Use May's calendar: Begin by identifying 06 May on a calendar, note that it’s Monday, and the total days in April (trust me, you’ll need this for smaller calculations) and days until last year (double trust me, you'll need this for larger calculations). From there, count backwards 173 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
Use excel: For more complex weeks calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-173 to get or =WORKDAY(TODAY()), -173, cell:cell) for working weeks.

Working weeks in 173 calendar weeks

173 weeks is Monday January 11, 2021 or could be if you only want workdays. This calculation takes 173 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday January 11, 2021 date.
