time formatting control
The Moon Times tab of the moon and sun options dialog contains the settings used to specify how to display the times of all Moon events of the currently selected DiaryGridLine (with the exception of the times of Moon phases whose settings are located in the moon phases tab).
You can specify how daily moon times (Moonrise, Moonset and Moon Transits) should be displayed, using the corresponding time formatting control.
In the case of Moon Transit times
there is an additional option Display Moon Transit times even on days when the moon does not rise and set
which can be used to determine what should happen to moon transit times when there are no moonrise and moonset (since moon transits are still defined
on those days).
For locations above 66 degrees north (and below 66 degrees south), there are recurring periods, covering many days, when the Moon never sets below, or never rises above, the horizon.
To display these times, you can use the moon above/below the horizon token and specify how you wish this effect to be displayed using the corresponding all day above/below horizon control.
