MongoDB Project Date ranges in mongoDB based on month or Quarter

Given a collection, I want to group ISODate by year and month and generate range of dates for each month.



For example if the dates are 10-10-2018, 11-10-2018, 11-10-2017, 04-04-2018
The output should be 



{"ranges": [

    {"min": 01-10-2018, "max": 31-10-2018}, 

    {"min": 01-10-2017, "max": 31-10-2017}, 

    {"min": 01-04-2018, "max": 31-04-2018}, 

]}


I could project month and year separately and group them and arrive at 



[Oct 2018, Oct 2017....]


Is there a way to arrive at the above output using mongo aggregate query






mongodb mongodb-query pymongo

  • docs.mongodb.com/manual/reference/operator/aggregation/…, then docs.mongodb.com/manual/reference/operator/aggregation/bucket if you know ranges or docs.mongodb.com/manual/reference/operator/aggregation/group if you don't.

  • Use the first link. Start of the month is "%Y-%m-01" End of the month is beginning of next month - 1 day, then "%Y-%m-%d" of the result.
