Bitcoin's story is a string of dates: the whitepaper on 31 October 2008, the first block on 3 January 2009, the pizza on 22 May 2010, every halving since. This tool reads the same timeline as BTCalendar and shows every event that fell on the day you pick, with how many years ago it was. Use the arrows to walk through the year, or open any event in BTCalendar for the full story and its source.
Only events with an exact day are listed; history known only to the month or year lives on BTCalendar's timeline. A day with nothing recorded shows the next day that has something. To get these anniversaries in your own calendar app, subscribe to BTCalendar.
