CheckiO Weekly #0 ― Clock Angle Review

Today we will examine the "Clock Angle" (http://www.checkio.org/mission/clock-angle/share/7defeec919a61f851255c46c1c9e12e5/) mission. You are given a time in 24-hour format and you should calculate a lesser angle between the hour and minute hands in degrees for analog clock. Simple mathematic model. But you can solve this even if you don't have doctor degree in Mathematics. Just watch at an analog clock. Old grandmother cuckoo-clock will be nice or find some video with analog clock (yeah it's sound weird).

Counting Time

Did you know that January 13th and January 14th mark the turn of the Old New Year? Because of the difference between the Julian and Gregorian calendars, the Julian calendar's New Years Eve and New Years day fall on these days on the Gregorian calendar, which is currently the most wide spread calendar in use.

Community Reviews: The Building Missions

A few weeks ago, we published missions devoted to World Urbanism Day. The first mission, “Building Base”, was a pilot for our OOP based missions. The second, “Inside Block”, was a reincarnation of the older mission “Target Hit” which some long time CheckiO players should remember. Today, we’ll be taking a close look at some of the more interesting and top scoring solutions.
