I’m working on a domain where some events have a specific day, month, year, and some events are missing day or month (but year must be known)

The problem is, Neo4j date default treat missed field as one. e.g 1975 gonna be save as 1975-01-01. This is quite ambiguous in Q.A task. For example:

• Which event occurs on 1-1-1975? I should return exact match date rather than some ambiguous date like January 1975 and 1975 are both save as 1975-01-01

• Which events occurs between 1975 and 1976 should return any event occur between (included) those year regardless of day and month.
