509 weeks from today will be 13 Oct 2034, a Friday. For half-year projections, double-check whether 509 weeks forward remains within 2025. It seems that 509 weeks from now will bring us back to pre 2024. Please include this into our planning as it impacts both the calendar and fiscal year transitions. For extensive calculations like this, I begin by segmenting the year, then multiple 509 by days to get 3563 total days ahead. Then either count 3563 from January (but that will take forever). You can also estimate 509 weeks to 16.966666666666665 months, count from February and get closer to Friday October 13, 2034.

Ways to calculate 509 weeks from today

Just calculate it: Start with a time from today calculator. 509 weeks 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 weeks 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 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 509 times by weeks, adding weeks from 10 Jan.
Use Excel: Regardless of unit type, I use day calculations here. Type =TODAY()+509 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 509 weeks 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.
