What was the date 721 weeks ago?

Solution

Saturday May 21, 2011

721 weeks ago from today was 21 May 2011, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 721 weeks from now will bring us back to pre 2024 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 5047 days on a calendar until getting my solution of Saturday May 21, 2011.

How we calculated 721 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 721 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 15 Mar, then set the calculation - 721 weeks, and factored in the year 2025
  2. Noted your current time of year: 721 weeks in March will bring us back to February or further.
  3. Counted backwards weeks from current day: date - 15 Mar, factoring in the 15 days left in March to calculate Saturday May 21, 2011
  4. 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 21

  • Current date: 15 Mar
  • Day of the week: Saturday
  • New Date: Saturday May 21, 2011
  • New Date Day of the week: Saturday
  • Counting backward from May could put you back in Q1 or even the previous year.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 721 weeks ago

  1. Calculate it: Start with a time ago calculator. 721 weeks is easiest solved on a calculator. For ours, we've already factored in the 15 days in March + 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!).
  2. Use March's calendar: Begin by identifying 15 Mar on a calendar, note that it’s Saturday, and the total days in February (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 721 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
  3. Use excel: For more complex weeks calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-721 to get or =WORKDAY(TODAY()), -721, cell:cell) for working weeks.

Working weeks in 721 calendar weeks

721 weeks is Saturday May 21, 2011 or could be if you only want workdays. This calculation takes 721 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday May 21, 2011 date.
