Solution

Monday January 29, 2024

100 days ago from today was 29 Jan 2024, a Monday. 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 May and April, alongside seasonal and calendar transitions. Since today is Wendesday, we'll actually need to start considering the weekend. Two days from now the weekend begins and it could throw off our calculation if we consider work days. Given we're in the middle of of May, with 8 days left out of the 31, 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 08 May, then set the calculation - 100 days, and factored in the year 2024
  2. Noted your current time of year: 100 days in May will bring us back to April or further.
  3. Counted backwards days from current day: date - 08 May, factoring in the 8 days left in May to calculate Monday January 29, 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 January 29

  • Current date: 08 May
  • Day of the week: Monday
  • New Date: Monday January 29, 2024
  • New Date Day of the week: Monday
  • 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.

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 8 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!).
  2. Use May's calendar: Begin by identifying 08 May on a calendar, note that it’s Monday, 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 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 Monday January 29, 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 Monday January 29, 2024 date.
