138 days ago from today was 19 Dec 2023, 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 May and April, alongside seasonal and calendar transitions. Since today is Sunday, the calculation could get a bit more complicated if you want to account for business days becuase it's the weekend. Given we're in the early part of of May, with 5 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 138 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 138 days ago gets calculated on each visit:

  1. We started with date inputs: used current day of 05 May, then set the calculation - 138 days, and factored in the year 2024
  2. Noted your current time of year: 138 days in May will bring us back to April or further.
  3. Counted backwards days from current day: date - 05 May, factoring in the 5 days left in May to calculate Tuesday December 19, 2023
  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 December 19

  • Current date: 05 May
  • Day of the week: Tuesday
  • New Date: Tuesday December 19, 2023
  • New Date Day of the week: Tuesday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.

Ways to calculate 138 days ago

  1. Calculate it: Start with a time ago calculator. 138 days is easiest solved on a calculator. For ours, we've already factored in the 5 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 05 May on a calendar, note that it’s Tuesday, 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 138 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()-138 to get or =WORKDAY(TODAY()), -138, cell:cell) for working days.

Working days in 138 calendar days

138 days is Tuesday December 19, 2023 or could be if you only want workdays. This calculation takes 138 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 December 19, 2023 date.
