I’ve defined in elasticsearch a field of type date in the format “MM-dd” which works fine except for the date 02-29.
I understand that elastic does use a year when saving (even though it doesn’t seem to affect the field) and the year elastic is using probably didn’t have the 29th in Feb.

I’ve tried saving the full year and letting elastic do the parse but elastic requires me to send the date in the same format.

any ideas of how I can save this value?

Thanks!
