How to work out 351 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.
351 days = 50 weeks + 1 day
The result falls 1 weekday before today's weekday. If today is a Monday, it was a Sunday.
In months, that's about 11.5, depending on the month lengths involved.
