What was the date 420 weeks ago?

Thursday November 10, 2016

420 weeks ago from today was 10 Nov 2016, a Thursday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 420 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 2940 days on a calendar until getting my solution of Thursday November 10, 2016.

How we calculated 420 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 420 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 28 Nov, then set the calculation - 420 weeks, and factored in the year 2024
Noted your current time of year: 420 weeks in November will bring us back to October or further.
Counted backwards weeks from current day: date - 28 Nov, factoring in the 28 days left in November to calculate Thursday November 10, 2016
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 10

Current date: 28 Nov
Day of the week: Thursday
New Date: Thursday November 10, 2016

In Novemeber, account for the end of the year holidays when counting backwards.
The solution crosses into a different year.

Ways to calculate 420 weeks ago

Calculate it: Start with a time ago calculator. 420 weeks is easiest solved on a calculator. For ours, we've already factored in the 28 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 28 Nov on a calendar, note that it’s Thursday, 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 420 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()-420 to get or =WORKDAY(TODAY()), -420, cell:cell) for working weeks.

Working weeks in 420 calendar weeks

420 weeks is Thursday November 10, 2016 or could be if you only want workdays. This calculation takes 420 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday November 10, 2016 date.
