[TW] : Hours of Twilight

Previous pageReturn to chapter overviewNext page

The [TW] Sun Token displays the total time between between dawn and sunrise plus the time between sunset and dusk. It is the difference in time between the [DL] and the [Srs] tokens.


[TWh] can be used to display only the hour part of the time.

[TWm] can be used to display only the minutes part of the time.


The source of data used to evaluate Sun Tokens comes from the Sun Data Source property.


The property Sun Options lets you specify how these times are displayed, and lets you specify which of the different solar depression angles should be used to correspond to various definitions of dawn and dusk (Astronomical, nautical, civil, ...).
