The number of weeks in a month varies, depending on which race's week you are using. For instance (ignoring the worship holidays that start and end each month) there are 16 ogre-weeks in a month, as they are only 3 days long (two days of work, one holiday.) There are only two gnome-weeks, however, as a gnome-week is 15 days long (they then have two days of rest between each of the two weeks.)
The city of Earth in The Heartland runs on its own system of time, for reasons unknown. In Earth, there are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute. This non-compliance with the rest of the world has caused Colk, God of Time, to boycott the city. No one in Earth seems to particularly mind this (or, indeed, to have noticed.)
Earth Conversion Rate
One normal second is 1.15740 "Earth-seconds". (6 earth-seconds is approximately 7 regular seconds.)
Every "Earth-minute" consisting of 60 "Earth-seconds" is equal to approximately 70 regular seconds, or .7 of a regular minute. Therefore every...this is where most people give up, and decide that it's simpler to just buy a watch from Earth. Working it out in any more detail sounds suspiciously like maths, which of course doesn't exist.
