Partial Dates within Craft Is it possible to store partial dates? EG i want to create a document that covers a date range, sometimes that range could be Jan/2013 to JUN/2014 other times we may need it more specific EG 20/JAN/2013 to FEB 2014 and sometimes even less specific like 2013-2015.

Would i need to create a new custom field type?
I'd set this up with regular date fields. You can then display the dates in whatever format you require on the front end using Twig's date formatting filter.

With the data stored as dates you can do a lot more with it compared to simply storing strings.

If you need to show a date range, such as "2013-2015" then it would probably be best to use 2 fields. A "date from" and a "date to" field. You could then use some logic to display one, or both, depending on whether there was something in the "date to" field.
