Leap Second Time Adjustment Day

Leap Second Time Adjustment Day is listed as a commemoration only. Scientists who have been around for many years do not make changes. But, if they do, it's either June 30 or December 31.

Make Up Your Mind Day

Make Up Your Mind Day, December 31st, encourages us to avoid wavering, to take a stand, and stick to it.
