How to work out 315 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.

315 days = 45 weeks + 0 days
The result falls on the same weekday as today.
In months, that's about 10.3, depending on the month lengths involved.
