Investigate changes in SERVER-53388: Week start parameter for $dateDiff aggregation expression

XMLWordPrintableJSON

      Description

      Downstream Change Summary

      $dateDiff function has been improved to support startOfWeek parameter that accepts English names or three letter abbreviations of days of a week. If the parameter is not specified, then a default of "Sunday" is used as opposed to "Monday" (previous behaviour).

      Description of Linked Ticket

      Add startOfWeek parameter to $dateDiff.

      The startOfWeek parameter denotes the starting position to use when the unit in $dateDiff is equal to "week".

      The accepted value can be a case-insensitive string which resolves to any of the following options: (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday). By default "Sunday" is considered the start of the week.
