What was the date 680 weeks ago?

Solution

Tuesday November 15, 2011

680 weeks ago from today was 15 Nov 2011, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 680 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 4760 days on a calendar until getting my solution of Tuesday November 15, 2011.

How we calculated 680 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 680 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 26 Nov, then set the calculation - 680 weeks, and factored in the year 2024
Noted your current time of year: 680 weeks in November will bring us back to October or further.
Counted backwards weeks from current day: date - 26 Nov, factoring in the 26 days left in November to calculate Tuesday November 15, 2011
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for November 15

Current date: 26 Nov
Day of the week: Tuesday
New Date: Tuesday November 15, 2011
New Date Day of the week: Tuesday
In Novemeber, account for the end of the year holidays when counting backwards.
The solution crosses into a different year.

Ways to calculate 680 weeks ago

Calculate it: Start with a time ago calculator. 680 weeks is easiest solved on a calculator. For ours, we've already factored in the 26 days in November + 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 November's calendar: Begin by identifying 26 Nov on a calendar, note that it’s Tuesday, and the total days in October (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 680 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()-680 to get or =WORKDAY(TODAY()), -680, cell:cell) for working weeks.

Working weeks in 680 calendar weeks

680 weeks is Tuesday November 15, 2011 or could be if you only want workdays. This calculation takes 680 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 November 15, 2011 date.
