While trying to work out when you guys go into European Summer Time I discovered there is a formula for determining such a day.
"Formula used to calculate the beginning of European Summer Time:
Sunday (31 - (5 * y ÷ 4 + 4) mod 7) March at 01:00 GMT
(valid until 2099[4]), where y is the year, and for the nonnegative a, a mod b is the remainder of division after truncating both operands to an integer."
Who would have thought it would be such a complicated exercise?
