Sunrise and Sunset Times Web Application

Shows the effect of permanent standard time or permanent daylight saving time for a location on Earth.

This web application provides an interface to select a location and view the sunrise and sunset times for the entire year. It uses Flask as the web framework, Plotly for data visualization, and the ephem library to calculate astronomical events.

Features

• Visualization of sunrise and sunset times across three scenarios: permanent standard time, current observance, and permanent daylight saving time.
• Interactive plots with hover information for precise sunrise and sunset times.
• Custom input fields for latitude, longitude, and a title for new locations.
• Menu for selection of predefined locations
