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, 19 Dec 2025.

Ways to calculate 343 days from today

  1. Just calculate it: Start with a time from today calculator. 343 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 January's calendar: Begin by identifying on a calendar, note that it’s Friday, 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 343 times by days, adding days from 10 Jan.
  3. Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+343 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 343 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.
