51 weeks ago from today was 14 Jan 2024, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 51 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 357 days on a calendar until getting my solution of Sunday January 14, 2024.

How we calculated 51 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 51 weeks ago gets calculated on each visit:

We started with date inputs: used current day of 05 Jan, then set the calculation - 51 weeks, and factored in the year 2025
Noted your current time of year: 51 weeks in January will bring us back to or further.
Counted backwards weeks from current day: date - 05 Jan, factoring in the 5 days left in January to calculate Sunday January 14, 2024
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 14

Current date: 05 Jan
Day of the week: Sunday
New Date: Sunday January 14, 2024
New Date Day of the week: Sunday
Counting back form January will put you close, if not passed, the previous year.
The solution crosses into a different year.

Ways to calculate 51 weeks ago

Calculate it: Start with a time ago calculator. 51 weeks is easiest solved on a calculator. For ours, we've already factored in the 5 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 05 Jan on a calendar, note that it’s Sunday, 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 51 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()-51 to get or =WORKDAY(TODAY()), -51, cell:cell) for working weeks.

Working weeks in 51 calendar weeks

51 weeks is Sunday January 14, 2024 or could be if you only want workdays. This calculation takes 51 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 January 14, 2024 date.
