Hi, i´m from a country that has daylight saving and the component showed a bug on that day. It happens becausa all date are created with hour set to 0, and the day which the daylight saving aplies has no hour zero, and it comes automatically to 23 pm of the previous day. I solved this locally by setting a hour on all dates instanciation. Any hour greater than 1 should do it. Since the component ignores the time part of date it should have no problem.
