There are two iterations of r/place, both starting on April 1st and ending on April 4th in their respective year.
The first iteration occured in 2017. The canvas was only a 1000x1000 grid, and only 16 colors were available. When placing pixels was suddenly locked on April 4th, the finished canvas was cemented as a piece of Internet history. The subreddit was left open for about a week or so after the event ended, before being archived with users being told to move to and . 2017's finished canvas was also displayed in the sidebar of the subreddit during the 2022 revival.
In 2022, r/place was revived. It started with a 1000x1000 grid and 16 options for colors, then expanded to 2000x1000 with 24 colors on April 2nd, and finally 2000x2000 with 32 colors on April 3rd. On April 4th, rather than a new expansion, all colors were locked and only white pixels were able to be placed. The entire canvas was reverted back to the original color in a matter of hours, and the option to place any pixels was locked afterwards.
In 2023, r/place was revived. It started on 20/07/2023 and ended on 25/07/2023. Many redditors wrote "FUCK SPEZ" on the canvas to protest the new API changes. On the last day, the color palette was changed to grayscale. Shortly after, it was changed to white. Redditors managed to write a giant "FUCK SPEZ" covering the entire canvas.
