A calendar that calculates leap years and can accurately display every single year of the standard Gregorian calendar (after the revision in 1752 that fundamentally changed the calendar). Press the left/right keys or click on the left/right side to change the month. Press the up/down keys or click on the up/down side to change the year. Press space or click in the center to bring up more options. This uses the Tomohiko Sakamoto Algorithm to calculate what day to start each month on. The following quora post has a good explanation on the algorithm. https://www.quora.com/How-does-Tomohiko-Sakamotos-Algorithm-work This project uses Pen Text Engine++ by @-Rex- The calendar has more display options that I didn't implement in this demo. Take this calendar with a grain of salt, as I haven't tested every year, so I can't confirm every year is correct, but the ones I've tested are. #calendar #pen #infinity
