+Go Date Parser
+---------------------------
+
+Parse many date strings without knowing format in advance. Uses a scanner to read bytes and use a state machine to find format. Much faster than shotgun based parse methods. See [bench_test.go](https://github.com/araddon/dateparse/blob/master/bench_test.go) for performance comparison.

+
+**MM/DD/YYYY VS DD/MM/YYYY** Right now this uses mm/dd/yyyy WHEN ambiguous if this is not desired behavior, use `ParseStrict` which will fail on ambiguous date strings.
+
+**Timezones** The location your server is configured affects the results! See example or https://play.golang.org/p/IDHRalIyXh and last paragraph here https://golang.org/pkg/time/#Parse.
+
+
+```go
+
+// Normal parse. Equivalent Timezone rules as time.Parse()
+t, err := dateparse.ParseAny("3/1/2014")
+
+// Parse Strict, error on ambigous mm/dd vs dd/mm dates
+t, err := dateparse.ParseStrict("3/1/2014")
+> returns error
+
+// Return a string that represents the layout to parse the given date-time.
+layout, err := dateparse.ParseFormat("May 8, 2009 5:57:51 PM")
+> "Jan 2, 2006 3:04:05 PM"
+
+```
