521 weeks ago from today was 20 May 2014, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 521 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 3647 days on a calendar until getting my solution of Tuesday May 20, 2014.

How we calculated 521 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 521 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 14 May, then set the calculation - 521 weeks, and factored in the year 2024
Noted your current time of year: 521 weeks in May will bring us back to April or further.
Counted backwards weeks from current day: date - 14 May, factoring in the 14 days left in May to calculate Tuesday May 20, 2014
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for May 20

Current date: 14 May
Day of the week: Tuesday
New Date: Tuesday May 20, 2014
New Date Day of the week: Tuesday
Counting backward from May could put you back in Q1 or even the previous year.
The solution crosses into a different year.

Ways to calculate 521 weeks ago

Calculate it: Start with a time ago calculator. 521 weeks is easiest solved on a calculator. For ours, we've already factored in the 14 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 14 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 521 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()-521 to get or =WORKDAY(TODAY()), -521, cell:cell) for working weeks.

Working weeks in 521 calendar weeks

521 weeks is Tuesday May 20, 2014 or could be if you only want workdays. This calculation takes 521 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 May 20, 2014 date.
