What was the date 78 weeks ago?

Sunday November 20, 2022

78 weeks ago from today was 20 Nov 2022, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 78 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 546 days on a calendar until getting my solution of Sunday November 20, 2022.

How we calculated 78 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 78 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 19 May, then set the calculation - 78 weeks, and factored in the year 2024
Noted your current time of year: 78 weeks in May will bring us back to April or further.
Counted backwards weeks from current day: date - 19 May, factoring in the 19 days left in May to calculate Sunday November 20, 2022
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 20

Current date: 19 May
Day of the week: Sunday
New Date: Sunday November 20, 2022
New Date Day of the week: Sunday
In Novemeber, account for the end of the year holidays 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 78 weeks ago

Calculate it: Start with a time ago calculator. 78 weeks is easiest solved on a calculator. For ours, we've already factored in the 19 days in May + 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 May's calendar: Begin by identifying 19 May on a calendar, note that it’s Sunday, and the total days in April (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 78 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()-78 to get or =WORKDAY(TODAY()), -78, cell:cell) for working weeks.

Working weeks in 78 calendar weeks

78 weeks is Sunday November 20, 2022 or could be if you only want workdays. This calculation takes 78 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 November 20, 2022 date.
