final berlinCalculator = DaylightCalculator(berlin);
final dailyResults = berlinCalculator.calculateForDay(DateTime.now(), Zenith.astronomical);
print(dailyResults.sunrise); // Some UTC datetime with sunrise hours like 08:32
print(dailyResults.sunset);
print(dailyResults.type); // day type, will probably be sunriseAndSunset unless you live near the north pole or south pole


double eventHourEpoch = berlinCalculator.calculateEvent(DateTime.now(), Zenith.official, EventType.sunset);
print(DateTime.fromMillisecondsSinceEpoch(eventHourEpoch.floor()));
