What was the date 66 weeks ago?

Solution

Sunday December 24, 2023

Date Range: 66 weeks

66 weeks ago from today was 24 Dec 2023, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 66 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 462 days on a calendar until getting my solution of Sunday December 24, 2023.

How we calculated 66 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 66 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 30 Mar, then set the calculation - 66 weeks, and factored in the year 2025
  2. Noted your current time of year: 66 weeks in March will bring us back to February or further.
  3. Counted backwards weeks from current day: date - 30 Mar, factoring in the 30 days left in March to calculate Sunday December 24, 2023
  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 December 24

  • Current date: 30 Mar
  • Day of the week: Sunday
  • New Date: Sunday December 24, 2023
  • New Date Day of the week: Sunday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.

Ways to calculate 66 weeks ago

  1. Calculate it: Start with a time ago calculator. 66 weeks is easiest solved on a calculator. For ours, we've already factored in the 30 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 30 Mar on a calendar, note that it’s Sunday, 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 66 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()-66 to get or =WORKDAY(TODAY()), -66, cell:cell) for working weeks.

Working weeks in 66 calendar weeks

66 weeks is Sunday December 24, 2023 or could be if you only want workdays. This calculation takes 66 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday December 24, 2023 date.
