This is the first launch of Tempus Calendar in beta! Tempus Calendar is a calendar application that I've been developing over the past year. It started out as a project of implementing multiple calendars, sundial time, and Jewish prayer times. Eventually, it grew to include the ability to calculate sunrise, sunset, and other times of day  on-demand without needing an internet connection. Since then, I have added a bunch of stuff to its custom-built GUI, as well as prayer times for Christians and Muslims. One of the latest additions has been Holidays for Christians and Jews and those in the US, as well as the ability to create custom events. Holidays for other religions or countries will be coming very soon, along with a better way to manage which ones are enabled.

Thanks for reading, and I hope you enjoy using the tool!

Note: Upgrades to new versions will be free for those who have already paid for a previous version.

How to Use
