Wednesday December 18, 2024

0

18 days ago from today was 18 Dec 2024, 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 Sunday, the calculation could get a bit more complicated if you want to account for business days becuase it's the weekend. This takes our subtraction across multiple weeks, and with 5 days until the end of January counting backwards from today in the early part of of the month means that subtracting 18 days ago will bring us back to or further.

How we calculated 18 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 18 days ago gets calculated on each visit:

We started with date inputs: used current day of 05 Jan, then set the calculation - 18 days, and factored in the year 2025
Noted your current time of year: 18 days in January will bring us back to or further.
Counted backwards days from current day: date - 05 Jan, factoring in the 5 days left in January to calculate Wednesday December 18, 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 December 18

Current date: 05 Jan
Day of the week: Wednesday
New Date: Wednesday December 18, 2024
New Date Day of the week: Wednesday
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 18 days ago

Calculate it: Start with a time ago calculator. 18 days is easiest solved on a calculator. For ours, we've already factored in the 5 days in January + 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 January's calendar: Begin by identifying 05 Jan on a calendar, note that it’s Wednesday, and the total days in (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 18 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()-18 to get or =WORKDAY(TODAY()), -18, cell:cell) for working days.

Working days in 18 calendar days

18 days is Wednesday December 18, 2024 or could be if you only want workdays. This calculation takes 18 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 December 18, 2024 date.
