How to work out 343 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.
343 days = 49 weeks + 0 days
The result falls on the same weekday as today.
In months, that's about 11.3, depending on the month lengths involved.
