Understanding FITS and Calendar Formats

FITS (Flexible Image Transport System) is a standard digital format used to store astronomical data, including images, spectra, and tables. While powerful for scientific analysis, FITS files aren't easily integrated into everyday scheduling or event planning tools. The Calendar format (.cal) is widely supported by applications like Google Calendar, Outlook, and Apple Calendar, making it ideal for managing appointments and events. Converting from FITS to Calendar allows you to visualize and schedule astronomical events, observations, or deadlines related to your research or hobby. This converter bridges the gap between specialized astronomical data and common scheduling practices.
