How to work out 129 days from today yourself

Split the number into full weeks and leftover days. Full weeks never change the weekday, so you only need the leftover days to find the weekday. Then step through the months, using each month's real length, to find the date.

129 days = 18 weeks + 3 days
The result falls 3 weekdays after today's weekday. If today is a Monday, it will be a Thursday.
In months, that's about 4.2, depending on the month lengths involved.
