How weeks between dates are counted
The calculator first counts the exact days between your dates, then divides by 7: the whole-number part is your full weeks and the remainder is the leftover days. That "X weeks, Y days" format is exactly how pregnancy is dated and how coaches write training blocks. The table also shows the same gap as a decimal week count and as calendar months.
