What was the date 30 days ago?

Solution

Wednesday March 19, 2025

Date Range: 30 days

30 days ago from today was 19 Mar 2025, a Wednesday. When calculating a period over two weeks in the past, it's important to account for the day of the week. 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. This takes our subtraction across multiple weeks, and with 18 days until the end of April counting backwards from today in the middle of of the month means that subtracting 30 days ago will bring us back to March or further.

How we calculated 30 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 30 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Apr, then set the calculation - 30 days, and factored in the year 2025
  2. Noted your current time of year: 30 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 Wednesday March 19, 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 March 19

  • Current date: 18 Apr
  • Day of the week: Wednesday
  • New Date: Wednesday March 19, 2025
  • New Date Day of the week: Wednesday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.

Ways to calculate 30 days ago

  1. Calculate it: Start with a time ago calculator. 30 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 Wednesday, 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 30 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()-30 to get or =WORKDAY(TODAY()), -30, cell:cell) for working days.

Working days in 30 calendar days

30 days is Wednesday March 19, 2025 or could be if you only want workdays. This calculation takes 30 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 March 19, 2025 date.
