Relaxed date/time field type?

I would like to use a date and/or time field that is less strict and can store just a year, or year&month.
When searching for available modules I only found "Partial Date" which is for version 7. Are there any other similar modules available for version 8?

Preferably the module could also handle date/time ranges.
For example "1999/09" is actually an implicit date range 1999/09/01 to 1999/09/30. Or an actual explicit range "2010 Jan" - "2015 Sep".
