Stephen Hackett has an update to his Apple History Calendar. He’s combined the dates from his three Kickstarter calendars into a single subscribable calendar that he’ll keep updating each month, so Apple anniversaries and milestones flow right into your calendar app.

It’s a one-time ten-dollar purchase, and backers of the original Kickstarters are getting updated versions of what they backed.

If you like knowing that today is the day some old Mac shipped, this one’s for you.
