+# Duration Parser
+
+Webpage to link to and parse ISO8601 durations. Like [durat.io](https://durat.io/) but the other way round
+
+A very quick and dirty hack using the following tools:
+
+- [tinyduration](https://github.com/MelleB/tinyduration)
+- [mvp.css](https://andybrewer.github.io/mvp/)
+
+Improvements will be gladly accepted
