How to work out 280 days ago 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.
280 days = 40 weeks + 0 days
The result falls on the same weekday as today.
In months, that's about 9.2, depending on the month lengths involved.
