What was the date 480 weeks ago?

Solution

Saturday May 16, 2015

0

480 weeks ago from today was 16 May 2015, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 480 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 3360 days on a calendar until getting my solution of Saturday May 16, 2015.

How we calculated 480 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 480 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 27 Jul, then set the calculation - 480 weeks, and factored in the year 2024
Noted your current time of year: 480 weeks in July will bring us back to June or further.
Counted backwards weeks from current day: date - 27 Jul, factoring in the 27 days left in July to calculate Saturday May 16, 2015
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 16

Current date: 27 Jul
Day of the week: Saturday
New Date: Saturday May 16, 2015
New Date Day of the week: Saturday
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.
Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 480 weeks ago

Calculate it: Start with a time ago calculator. 480 weeks is easiest solved on a calculator. For ours, we've already factored in the 27 days in July + 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 July's calendar: Begin by identifying 27 Jul on a calendar, note that it’s Saturday, and the total days in June (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 480 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()-480 to get or =WORKDAY(TODAY()), -480, cell:cell) for working weeks.

Working weeks in 480 calendar weeks

480 weeks is Saturday May 16, 2015 or could be if you only want workdays. This calculation takes 480 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday May 16, 2015 date.
