480 days from today is 14 Sep 2026, a Monday. Adding 480 days, or anything around or above six months ahead from today, brings a layer of annual planning to the calculation. Since today is Thursday, we'll have to adjust for the weekend, if you care about the number of work days. We’re in the end of of May so we’ll first need to consider the 9 days left in the month. This will help us understand how many weekends, work days, holidays, or days beyond May or June we’ll need to account for before getting to our new date, 14 Sep 2026.

How we calculated 480 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 480 days to today's date gets calculated on each visit:

  • Started with date inputs: starting point: 22 May, Units to add: 480 days, and year: 2025
  • Noted your current time of year: 9 days in end of May
  • Added 480 days from current day: 22 May, factoring in there are 9 days left in before June
  • Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Ways to calculate 480 days from today

  1. Just calculate it: Start with a time from today calculator. 480 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 2025. 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 on a calendar, note that it’s Monday, and the total days in June (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 480 times by days, adding days from 22 May.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+480 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 480 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.
