Day view

[jhanarato]

For a given day we can provide the following view of the data:

• What season are we in?
• Is today the uposatha?
• Number of days to the next uposatha
• Details of the next uposatha
• Is the next uposatha a holiday?

Also, is today before, during or after the rains retreat?

Most of the time we can just get the next Season/Uposatha pair. However, if today is the uposatha and we want to show the subsequent uposatha and today is the last day of the season we'll need to look ahead.

Maybe just go simple and not show the next uposatha if today is the uposatha.
