Date format and keyword recognition

Can more date formats and natural keywords be recognised without requiring `@`? Ideally, starting with `01/01/1970` and `today` would be most useful. **Formats:** - `01/01/1970` - `01.01.1970` - `01-01-1970` - `1970/01/01` - etc. **Keywords:** - `today` - `tomorrow` - `Monday` - next Monday - `last Friday` - etc.
