Mongo 3.6 can epoch date be converted to date

I am using a mongo 3.6 db. The collection I am querying with stores a date as epoch date. in mongo 4.x there is a date$ function which can convert it. Can this be done in 3.6 and if so anyone have a example ?

Hello @James_Shreckengost, welcome to the community.

There are Aggregation Date Operators to work with dates from other formats. You can use them in your find and aggregate queries.
