+# datetime
+
+Simple helper to help parse date strings into `Date`, with additionnal functions.
+
+## Usage
+
+### parseDate / parseDateTime
+
+- `parseDate()` - Take an input string and a format to parse the date. Supported 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("03-01-2019", "dd-mm-yyyy") // output : new Date(2019, 1, 3)
+parseDate("2019-01-03", "yyyy-mm-dd") // output : new Date(2019, 1, 3)
+...
+
+parseDateTime("01-03-2019 16:34", "mm-dd-yyyy hh:mm") // output : new Date(2019, 1, 3, 16, 34)
+parseDateTime("16:34 01-03-2019", "hh:mm mm-dd-yyyy") // output : new Date(2019, 1, 3, 16, 34)
+...
+```
+
+### dayOfYear / currentDayOfYear
+
+- `dayOfYear()` - Returns the number of the day in the year.
+- `currentDayOfYear()` - Returns the number of the current day in the year.
+
+```ts
+import {
+  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 :) **
+```
