In a leap year that starts on a Thursday, the calendar has a unique pattern. For example, the ISO year for these years has 53 weeks instead of the usual 52. This means there's an extra week in the year. This extra week shifts the dates of later weeks. For instance, ISO week 10, which usually starts around March 1st, will begin a bit earlier in these special years.
