What was the date 470 weeks ago?


Tuesday May 19, 2015


470 weeks ago from today was 19 May 2015, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 470 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 3290 days on a calendar until getting my solution of Tuesday May 19, 2015.

How we calculated 470 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 470 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 21 May, then set the calculation - 470 weeks, and factored in the year 2024
  2. Noted your current time of year: 470 weeks in May will bring us back to April or further.
  3. Counted backwards weeks from current day: date - 21 May, factoring in the 21 days left in May to calculate Tuesday May 19, 2015
  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 19

  • Current date: 21 May
  • Day of the week: Tuesday
  • New Date: Tuesday May 19, 2015
  • 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 470 weeks ago

  1. Calculate it: Start with a time ago calculator. 470 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!).
  2. 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 470 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()-470 to get or =WORKDAY(TODAY()), -470, cell:cell) for working weeks.

Working weeks in 470 calendar weeks

470 weeks is Tuesday May 19, 2015 or could be if you only want workdays. This calculation takes 470 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 19, 2015 date.
