What was the date 90 days ago?

Solution

Saturday January 18, 2025

Date Range: 90 days

90 days ago from today was 18 Jan 2025, a Saturday. Calculating time over multiple months means we must count back weeks and weekends + the 30 April, typically moving from the middle of April into March and potentially further. Since today is Friday, well need to account for the weekend if you care about work days. If not, the calculation will remain the same. The key difference with subtracting two+ months, compared to shorter spans, is the need to consider several weekends from the middle of April to get Saturday January 18, 2025.

How we calculated 90 days 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 90 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Apr, then set the calculation - 90 days, and factored in the year 2025
  2. Noted your current time of year: 90 days in April will bring us back to March or further.
  3. Counted backwards days from current day: date - 18 Apr, factoring in the 18 days left in April to calculate Saturday January 18, 2025
  4. 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 18

  • Current date: 18 Apr
  • Day of the week: Saturday
  • New Date: Saturday January 18, 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 90 days ago

  1. Calculate it: Start with a time ago calculator. 90 days is easiest solved on a calculator. For ours, we've already factored in the 18 days in April + all number of days in each month and the number of days in . Simply add your days and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use April's calendar: Begin by identifying 18 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 90 times days by days, subtracting days from until your remainder of days is 0.
  3. Use excel: For more complex days calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-90 to get or =WORKDAY(TODAY()), -90, cell:cell) for working days.

Working days in 90 calendar days

90 days is Saturday January 18, 2025 or could be if you only want workdays. This calculation takes 90 days 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 18, 2025 date.
