Blue Hour

A small utility application that computes the so called "Blue hour" intervals for the current position. The application computes the hours for the next 5, 15 or 30 days. By selecting an interval from the list, the user can push a new event to the default calendar.
The application also delivers weather information for the immediate period (max 9 days). The weather forecasts are based on Norwegian Meteorological Institute data. User can opt-out of weather data, in order to preserve bandwidth (useful in roaming mode).
