Date range query - 29 of February in "MMdd" format issue

I encountered a difficulty when trying to query on
"field_name": {
"type": "date",
"format": "MMdd"
}
field. It happened for "0229" date and I got message "failed to parse date field [0229] with format [MMdd]". What shall I do considering 29 of February a valid date for leap years.

I you don't use a year, than the current is suspected.
But in 2018 there is no 29. 2..

Try using it with year, it should work.

Thanks @Mojster for your response.
I'm aware that it would work if the year is added, but in my case it must not be year dependent.
