What was the date 150 weeks ago?

Solution

Monday February 21, 2022

150 weeks ago from today was 21 Feb 2022, a Monday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 150 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 1050 days on a calendar until getting my solution of Monday February 21, 2022.

How we calculated 150 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 150 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 06 Jan, then set the calculation - 150 weeks, and factored in the year 2025
Noted your current time of year: 150 weeks in January will bring us back to or further.
Counted backwards weeks from current day: date - 06 Jan, factoring in the 6 days left in January to calculate Monday February 21, 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 February 21

Current date: 06 Jan
Day of the week: Monday
New Date: Monday February 21, 2022
New Date Day of the week: Monday
Remember February has 28 or 29 days depending on Leap Year! This may not impact time in the past, but it will impact future dates.
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 150 weeks ago

Calculate it: Start with a time ago calculator. 150 weeks is easiest solved on a calculator. For ours, we've already factored in the 6 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 06 Jan on a calendar, note that it’s Monday, 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 150 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()-150 to get or =WORKDAY(TODAY()), -150, cell:cell) for working weeks.

Working weeks in 150 calendar weeks

150 weeks is Monday February 21, 2022 or could be if you only want workdays. This calculation takes 150 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday February 21, 2022 date.
