+
+Returns the quarter and year to which the supplied date belongs to.
+
+- Use `Date.prototype.getMonth()` to get the current month in the range (0, 11), add `1` to map it to the range (1, 12).
+- Use `Math.ceil()` and divide the month by `3` to get the current quarter.
+- Use `Date.prototype.getFullYear()` to get the year from the given date.
+- Omit the argument, `date`, to use the current date by default.
+
+```js
+const quarterOfYear = (date = new Date()) => [
+  Math.ceil((date.getMonth() + 1) / 3),
+  date.getFullYear(),
+];
+```
+
+```js
+quarterOfYear(new Date('07/10/2018')); // [ 3, 2018 ]
+quarterOfYear(); // [ 4, 2020 ]
+```
