@ -8,7 +8,20 @@ Parse any date string without knowing format in advance. Uses a scanner to read
**Timezones** The location your server is configured effects the results! See example or https://play.golang.org/p/IDHRalIyXh and last paragraph here https://golang.org/pkg/time/#Parse.
See example https://github.com/araddon/dateparse/blob/master/example/main.go
```go
// Normal parse
t, err := dateparse.ParseAny("3/1/2014")
// Parse with Location
denverLoc, _ := time.LoadLocation("America/Denver")
t, err := dateparse.ParseIn("3/1/2014", denverLoc)
```
Extended example https://github.com/araddon/dateparse/blob/master/example/main.go
```go
package main
