		Determine if a day is a GO! GO! Day.
		Determine if a day is a [GO! GO! Day](https://gogocurryamerica.com/).

		```js
		const { isGoGoDay } = require( '@quartz/is-go-go-day' );

		console.log( isGoGoDay() );

		console.log( isGoGoDay( new Date('2020-01-14') ) );

		console.log( isGoGoDay( new Date('2020-01-15T00:00:00-05:00') ) );
		```

		Or get a list of all GO! GO! Days for a given year.

		```js
		const { getGoGoDays } = require( '@quartz/is-go-go-day' );

		console.log ( getGoGoDays( 2020 ) );
