355 days from today is 31 Dec 2025, a Wednesday. Adding 355 days, or anything around or above six months ahead from today, brings a layer of annual planning to the calculation. 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. We’re in the middle of of January so we’ll first need to consider the 21 days left in the month. This will help us understand how many weekends, work days, holidays, or days beyond January or February we’ll need to account for before getting to our new date, 31 Dec 2025.

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 355 days to today's date gets calculated on each visit:

Started with date inputs: starting point: 10 Jan, Units to add: 355 days, and year: 2025
Noted your current time of year: 21 days in middle of January
Added 355 days from current day: 10 Jan, factoring in there are 21 days left in before February
Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the 2025 fiscal calendar.

Ways to calculate 355 days from today

Just calculate it: Start with a time from today calculator. 355 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 January's calendar: Begin by identifying on a calendar, note that it’s Wednesday, and the total days in February (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 355 times by days, adding days from 10 Jan.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+355 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 355 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.

355 days is Wednesday December 31, 2025 or could be Friday May 22, 2026 if you only want workdays. This calculation takes 355 days and only adds by the number of workdays in a week.
