To find a relative date, 14 weeks in the future from a starting point like 1st September, you can manually calculate it by breaking it down into simpler steps. First, determine the number of days in 14 weeks (14 weeks x 7 days/week = 98 days). Next, add these 98 days to 1st September to get the future date.

For example, calculating 14 weeks in the future from 1st September:

1st September + 98 days = 9th December.

By following this method, you can accurately find a relative date in the future based on a given starting date. Calculating date differences like this can be useful for planning events, scheduling tasks, or setting deadlines accurately. With a simple formula and a basic understanding of days and weeks, finding future dates manually becomes straightforward and efficient.
