+# Four Twenty Clock
+
+A clock that tells when and where it's going to be [4:20](https://en.wikipedia.org/wiki/420_(cannabis_culture%29) next
+
+![screensot](screenshot.png) ![screenshot at 4:20](screenshot1.png)
+
+## Note
+
+Once in a while, there'd be updates to the [timezone database](https://timezonedb.com/download) which
+would require updating `fourTwentyTz.js`. I'll do my best to release a new version every time this happens,
+but if you ever need to do this yourself, just run `python mkFourTwentyTz.py` (after downloading the timezone CSV files.
+See comment at the top of the script).
