What was the date 450 weeks ago?

Solution

450 weeks ago from today was 25 May 2016, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 450 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 3150 days on a calendar until getting my solution of Wednesday May 25, 2016.

How we calculated 450 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 450 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 08 Jan, then set the calculation - 450 weeks, and factored in the year 2025
Noted your current time of year: 450 weeks in January will bring us back to or further.
Counted backwards weeks from current day: date - 08 Jan, factoring in the 8 days left in January to calculate Wednesday May 25, 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 May 25

Current date: 08 Jan
Day of the week: Wednesday
New Date: Wednesday May 25, 2016
New Date Day of the week: Wednesday
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.

Ways to calculate 450 weeks ago

Calculate it: Start with a time ago calculator. 450 weeks is easiest solved on a calculator. For ours, we've already factored in the 8 days in January + 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 January's calendar: Begin by identifying 08 Jan on a calendar, note that it’s Wednesday, and the total days in (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 450 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()-450 to get or =WORKDAY(TODAY()), -450, cell:cell) for working weeks.

Working weeks in 450 calendar weeks

450 weeks is Wednesday May 25, 2016 or could be if you only want workdays. This calculation takes 450 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday May 25, 2016 date.
