california-clock-change generates the wrong date for months that start on a Sunday

The code for calculating the second Sunday in March doesn't work this year (2026) because March starts with a Sunday.

                // Second Sunday in March
                const springForward = new Date(y, 2, 1 + (14 - new Date(y, 2, 1).getDay()));

Should probably be something like:

                // Second Sunday in March
                let firstDayInMarchDay = new Date(y, 2, 1).getDay();
                let firstSundayInMarchDay = 1 + (7 - firstDayInMarchDay) % 7;
                let secondSundayInMarchDay = firstSundayInMarchDay + 7;
                const springForward = new Date(y, 2, secondSundayInMarchDay);

There's also a similar bug for November, which only is an issue when November 1st is a Sunday (also happens in 2026).
