What was the date 17 weeks ago?

Solution

Tuesday January 23, 2024

17 weeks ago from today was 23 Jan 2024, a Tuesday. We’re now subtracting quarters of the year. This means 17 weeks from 21 May changes fiscal calendars and could even push us into previous years. We’re currently in end of May with 21 days left; this will keep us in May and we don’t need to worry about adjusting months or years. When I calculate backwards for larger weeks before today, I like to start by subtracting the days, then count backwards to find the correct weeks.

How we calculated 17 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 17 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 21 May, then set the calculation - 17 weeks, and factored in the year 2024
Noted your current time of year: 17 weeks in May will keep us in May and we don’t need to worry about adjusting months or years.
Counted backwards weeks from current day: date - 21 May, factoring in the 21 days left in May to calculate Tuesday January 23, 2024
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 23

Current date: 21 May
Day of the week: Tuesday
New Date: Tuesday January 23, 2024
New Date Day of the week: Tuesday
Counting back form January will put you close, if not passed, the previous year.
This calculation crosses at least one month. Remeber, this will change our day of the week.

Ways to calculate 17 weeks ago

Calculate it: Start with a time ago calculator. 17 weeks is easiest solved on a calculator. For ours, we've already factored in the 21 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 21 May on a calendar, note that it’s Tuesday, 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 17 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()-17 to get or =WORKDAY(TODAY()), -17, cell:cell) for working weeks.

Working weeks in 17 calendar weeks

17 weeks is Tuesday January 23, 2024 or could be if you only want workdays. This calculation takes 17 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday January 23, 2024 date.
