100 days from today is 25 May 2025, a Sunday. Calculating the number of days that spans over three months from today moves us beyond mere day-to-day counting and into the realm of weekly and monthly converting which is mostly used in the fiscal calendar. We’ll need to consider the day of the week, length of February and March (and more), and the changing of the calendar. To start, today is a Sunday. 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.. Additionally, there are 14 days left of the 28 in February and since we’re in the middle of of the month, we’ll need to factor in shifting weekends of that quarter. Ultimately, adding if 100 days from today is difficult when the number is over a quarter and I’d recommend starting with a week conversion first.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how adding 100 days to today's date gets calculated on each visit:
Sunday Sunday May 25, 2025 is the 145 day of the year or 39.73% through 2025.
100 days is Sunday May 25, 2025 or could be Friday July 04, 2025 if you only want workdays. This calculation takes 100 days and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday May 25, 2025 date.
