The earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?
How to know the time zones.
Given exactly 360° in a circle and 365.24 days in a year, how many degrees per day does one's view of the night sky shift? (This assumes one looks in exactly the same direction, at the meridian - the middle of the sky defined by a line across it running due north to due south, at exactly the same time each night.)
