What's the date 500 days from today?

Solution

Wednesday September 10, 2025

if 500 days from today is 10 Sep 2025, a Wednesday. Adding 500 days, or anything around or above six months ahead from today, brings a layer of annual planning to the calculation. 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. We’re in the middle of of April so we’ll first need to consider the 20 days left in the month. This will help us understand how many weekends, work days, holidays, or days beyond April or May we’ll need to account for before getting to our new date, 10 Sep 2025.

How we calculated 500 days from 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 adding 500 days to today's date gets calculated on each visit:

Started with date inputs: starting point: 28 Apr, Units to add: 500 days, and year: 2024
Noted your current time of year: 500 days in middle of April will bring us into May. (Or far beyond).
Added 500 days from current day: 28 Apr, factoring in there are 20 days left in before May
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2024 fiscal calendar.

Ways to calculate 500 days from today

Just calculate it: Start with a time from today calculator. 500 days is easiest solved on a calculator. For ours, we've already factored in the days in + all number of days in each month and the number of days in 2024. 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 April's calendar: Begin by identifying on a calendar, note that it’s Wednesday, and the total days in May (trust me, you’ll need this for smaller calculations) and days until next year (double trust me, you'll need this for larger calculations). From there, count forward 500 times by days, adding days from 28 Apr.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+500 into the cell. If you want to add weeks, multiply your day by 7 and months/years will take their own calculation due to the changing days of the week. To find 500 days workdays, convert to days but use =WORKDAY(TODAY(), [number of days], [holidays]) into the cell. [number of days] is how many working days you want to add, and [holidays] is an optional range of cells that contain dates of holidays to exclude.

500 days is Wednesday September 10, 2025 or could be Sunday March 29, 2026 if you only want workdays. This calculation takes 500 days and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday September 10, 2025 date.
