What was the date 90 days ago?

Solution

Wednesday February 21, 2024

0

90 days ago from today was 21 Feb 2024, a Wednesday. Calculating time over multiple months means we must count back weeks and weekends + the 31 May, typically moving from the end of May into April and potentially further. Since today is Tuesday and still part of the beginning of the week we won't need to add additional days into next week. The key difference with subtracting two+ months, compared to shorter spans, is the need to consider several weekends from the end of May to get Wednesday February 21, 2024.

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:

We started with date inputs: used current day of 21 May, then set the calculation - 90 days, and factored in the year 2024
Noted your current time of year: 90 days in May will bring us back to April or further.
Counted backwards days from current day: date - 21 May, factoring in the 21 days left in May to calculate Wednesday February 21, 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 February 21

Current date: 21 May
Day of the week: Wednesday
New Date: Wednesday February 21, 2024
New Date Day of the week: Wednesday
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.

Ways to calculate 90 days ago

Calculate it: Start with a time ago calculator. 90 days is easiest solved on a calculator. For ours, we've already factored in the 21 days in May + 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!).
Use May's calendar: Begin by identifying 21 May on a calendar, note that it’s Wednesday, 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 90 times days by days, subtracting days from until your remainder of days is 0.
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 Wednesday February 21, 2024 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 Wednesday February 21, 2024 date.
