100 days ago from today was 13 Aug 2024, a Tuesday. Subtracting a number of days that spans over three months takes us beyond simple day-to-day subtraction into calculating across weeks and months, crucial for understanding fiscal calendars. Considerations include the day of the week, and the length of both November and October, alongside seasonal and calendar transitions. Since today is Thursday, we'll have to adjust for the weekend, if you care about the number of work days. Given we're in the end of of November, with 21 days left out of the 30, factoring in shifting weekends of that quarter becomes essential. For such extensive backward calculations, starting with week-by-week or month-by-month subtraction might offer clearer insights.

How we calculated 100 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 100 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 21 Nov, then set the calculation - 100 days, and factored in the year 2024
  2. Noted your current time of year: 100 days in November will bring us back to October or further.
  3. Counted backwards days from current day: date - 21 Nov, factoring in the 21 days left in November to calculate Tuesday August 13, 2024
  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 August 13

  • Current date: 21 Nov
  • Day of the week: Tuesday
  • New Date: Tuesday August 13, 2024
  • New Date Day of the week: Tuesday
  • August is the beginning of Q3. Dates in previous months will be part of 1H fiscal years.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.

Ways to calculate 100 days ago

  1. Calculate it: Start with a time ago calculator. 100 days is easiest solved on a calculator. For ours, we've already factored in the 21 days in November + 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 November's calendar: Begin by identifying 21 Nov on a calendar, note that it’s Tuesday, and the total days in October (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 100 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()-100 to get or =WORKDAY(TODAY()), -100, cell:cell) for working days.

Working days in 100 calendar days

100 days is Tuesday August 13, 2024 or could be if you only want workdays. This calculation takes 100 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday August 13, 2024 date.
