[Haskell-beginners] Simple data type for dates?

[Matthew Low]

The `time` package equivalent of `MyDate` would be `Day`:

storeDate :: Day
storeDate = fromGregorian 2021 6 29

> storeDate
2021-06-29
> toGregorian storeDate
(2021,6,29)
> dayOfWeek storeDate
Tuesday

However, I don't see any easy conversion between the numeric month and its
English name.
