How to work out 15 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.
15 days = 2 weeks + 1 day
The result falls 1 weekday after today's weekday. If today is a Monday, it will be a Tuesday.
In months, that's about 0.5, depending on the month lengths involved.
