|
|
formats are exported in `DateFormat`.
|
|
- `parseDateTime()` - Take an input string and a format to parse the dateTime.
|
|
Supported formats are exported in `DateTimeFormat`.
|
|
|
|
```ts
|
|
import { parseDate, parseDateTime } from 'https://deno.land/std/datetime/mod.ts'
|
|
|
|
parseDate("20-01-2019", "dd-mm-yyyy") // output : new Date(2019, 0, 20)
|
|
parseDate("2019-01-20", "yyyy-mm-dd") // output : new Date(2019, 0, 20)
|
|
...
|
|
|
|
parseDateTime("01-20-2019 16:34", "mm-dd-yyyy hh:mm") // output : new Date(2019, 0, 20, 16, 34)
|
|
parseDateTime("16:34 01-20-2019", "hh:mm mm-dd-yyyy") // output : new Date(2019, 0, 20, 16, 34)
|
|
...
|
|
```
|
|
|
|
### dayOfYear / currentDayOfYear
|
|
|
|

} from "https://deno.land/std/datetime/mod.ts";
|
|
|
|
dayOfYear(new Date("2019-03-11T03:24:00")); // output: 70
|
|
currentDayOfYear(); // output: ** depends on when you run it :) **
|
|
```
|
|
|
|
