Setting the 24-hour/lunar age dials
4. Find out the lunar age.
* Look up the next day's lunar age (lunar age at noon) in a newspaper or on
the Internet. As the lunar age advances by 1 every day, you can find out
the current lunar age by converting hours from current time to the next
day's noon into day and subtract the value from the next day's lunar age.
For example, if the next day's lunar age is 5.8 (lunar age at noon) and it is
17:00 of the current day, convert 19 hours (from 17:00 to the next 12:00)
into 0.8 days (19/24 = approx. 0.8) and subtract the value from 5.8, and
you get 5 as the current lunar age.
5. Check the difference between longitude of the observation point and
that of standard time covering the point.
