587 days from today is 28 Sep 2026, a Monday. Adding 587 days, or anything around or above six months ahead from today, brings a layer of annual planning to the calculation. Since today is Tuesday and still part of the beginning of the week we won't need to add additional days into next week. We’re in the middle of of February so we’ll first need to consider the 10 days left in the month. This will help us understand how many weekends, work days, holidays, or days beyond February or March we’ll need to account for before getting to our new date, 28 Sep 2026.

Ways to calculate 587 days from today

Just calculate it: Start with a time from today calculator. 587 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!).
Use February's calendar: Begin by identifying on a calendar, note that it’s Monday, and the total days in March (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 587 times by days, adding days from 18 Feb.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+587 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 587 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.
