311 days from today is 30 Sep 2025, a Tuesday. Adding 311 days, or anything around or above six months ahead from today, brings a layer of annual planning to the calculation. Since today is Saturday, the calculation could be adjusted for work days. But If you just want the overall days, nothing will change. We’re in the end of of November so we’ll first need to consider the 7 days left in the month. This will help us understand how many weekends, work days, holidays, or days beyond November or December we’ll need to account for before getting to our new date, 30 Sep 2025.

Ways to calculate 311 days from today

  1. Just calculate it: Start with a time from today calculator. 311 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!).
  2. Use November's calendar: Begin by identifying on a calendar, note that it’s Tuesday, and the total days in December (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 311 times by days, adding days from 23 Nov.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+311 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 311 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.
