Most of the time we only need date part of  iso date in any document during an aggregation. Here is how to get the date part for aggregation,

  1. Project ( $project ) as a new filed, say “considered_date”
  2. Group with the field


{$match : {  any filtering with $match }}
,{$project : { _id :1 , any project fileds
, “considered_date” : ¬† ¬† ¬†{“$concat” : [
{“$substr” : [{“$dayOfMonth” : “$date_1”}, 0, 2]}, “-“,
{“$substr” : [{“$month” : “$date_1”}, 0, 2]}, “-“,
{“$substr” : [{“$year” : “$date_1”}, 0, 4]}
