How to enter incomplete or partial date with date module? (Day-Month-Year / Month-Year / Year)

Question

I have a content type A and it has a date field.

I'm selecting Day-Month-Year for this date field. But not every content has a day and I want to select only Month and Year for these content.

If I select (enter) only month and year, it gives error:

The value input for field Date is invalid: The value March 1979 does not match the expected format.

I installed and tried the Partial Date module but still couldn't do what I want although it says on the module page:

This module provides date and time fields that allows any individual component to be left blank, while still providing a sortable listing of the fields.

How can I do that? I want to enter full date (Day-Month-Year) for some nodes and for some others partial date (only Month-Year) and maybe for some others only Year. Isn't this possible?

• Day-Month-Year
• Month-Year
• Year

(And also there is an unsolved issue about this: Allow "fuzzy" granularity.)

Answer 1

It is not possible with one date field. But you can achieve it by adding two different date fields with different configuration i.e.:

• Date, Month and Year for Date1 field.
• only Month and Year for Date2 field.

Answer 2

The only way do to that is to set the widget type to Select, and omit the Day part, as seen in the below screenshot.

UPDATE: I don't know why I haven't read the question completely; but Nikhil is right, the only way is create two Date components with different configurations.

Answer 3

Create three different Date fields, using different date formats. You can specify the Date entry option during Date field creation (click on More settings and values and choose Custom format in Date entry options, the custom input format for only a month would be F, for example)
