What was the date 13 weeks ago?

Solution

Saturday January 11, 2025

Date Range: 13 weeks

13 weeks ago from today was 11 Jan 2025, a Saturday. We’re now subtracting quarters of the year. This means 13 weeks from 12 Apr changes fiscal calendars and could even push us into previous years. We’re currently in middle of April with 12 days left; this will bring us back to March or further. When I calculate backwards for larger weeks before today, I like to start by subtracting the days, then count backwards to find the correct weeks.

How we calculated 13 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 13 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 12 Apr, then set the calculation - 13 weeks, and factored in the year 2025
Noted your current time of year: 13 weeks in April will bring us back to March or further.
Counted backwards weeks from current day: date - 12 Apr, factoring in the 12 days left in April to calculate Saturday January 11, 2025
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for January 11

Current date: 12 Apr
Day of the week: Saturday
New Date: Saturday January 11, 2025
New Date Day of the week: Saturday
Counting back form January will put you close, if not passed, the previous year.
This calculation crosses at least one month. Remeber, this will change our day of the week.
Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 13 weeks ago

Calculate it: Start with a time ago calculator. 13 weeks is easiest solved on a calculator. For ours, we've already factored in the 12 days in April + 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 April's calendar: Begin by identifying 12 Apr on a calendar, note that it’s Saturday, and the total days in March (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 13 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()-13 to get or =WORKDAY(TODAY()), -13, cell:cell) for working weeks.

Working weeks in 13 calendar weeks

13 weeks is Saturday January 11, 2025 or could be if you only want workdays. This calculation takes 13 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 January 11, 2025 date.
