             The algorithm prioritizes filling the shortest gaps first. It optimizes for spreading your holidays throughout the year to create the most number of consecutive vacation periods.

+        <p>
+            For the calculation, it counts all vacation stretches that are 3 days or longer, including those lucky 3-day weekends thanks to public holidays. It's slightly optimistic, but captures the spirit of maximising time off.
