### Input
Supported formats:
* Epoch time (in number form)
* `YYYY-MM-DD`
* `[+-]YYYYYY[Y...]-MM-DD`
* `[DDD, ]DD MMM YYYY`
* `M[M]/D[D]/YY[YY]` (1)

* `[-]Y[Y...] M[M] D[D]` (2)
* `D[D] MMM Y[Y...]` (2)
* `[-]Y[Y...] MMM D[D]` (2)
* `M[M] [-]Y[Y...]` (3, 5)

* `MMM [-]Y[Y...]` (3, 5)
* `[-]Y[Y...] MMM` (3, 5)

Generally, formats support trailing parts, which are disregarded.
1. When the former of these formats overlaps with the latter, the
former is preferred
2. " ", ".", "-" and "/" are all supported as separator
3. Any sequence of non-alphanumerical characters are supported as
separator
4. This format is only assumed if the year is bigger than the month
5. This format doesn't support trailing parts
### API
**`parse(String date[, String endDate]) -> Object`**
* `String date`: Any date
* `String endDate` <sup>optional</sup>: Any date; when added, the first parameter is treated as the
start date of the range.
**`format(Object date[, String delimiter = '-']) -> String`**
* `Object date`: Any date
* `String delimiter` <sup>optional</sup>: Separate parts by delimiter
---
Here, `Object date` (CSL-JSON date format) can have the following properties:
* `date-parts`: array with one or two dates, each date being an array of [year, month, day], the last two parts being optional
* `raw`: raw date
