Reshaping date format

Hi everyone.

I would like to build a code that transforms my current format into a desired format for my dates. Both formats should be kept as General. Please find below some examples:

Current format: 1/1/2018 12:00:00 AM
Target format: All : [1/1/2018,2/1/2018)

Current format: 2/1/2018 12:00:00 AM
Target format: All : [2/1/2018,3/1/2018)

Current format: 10/1/2018 12:00:00 AM
Target format: All : [10/1/2018,11/1/2018)


In the target format I add some text, ignore the 12:00:00 AM part, and include in bracket current month and next month.

I would really appreciate your help to build this formula.

Thank you.

David
