dateRange property
This is used for FIRST_VISIT_DATE cohort, the cohort selects users whose
first visit date is between start date and end date defined in the
DateRange.
The date ranges should be aligned for cohort requests. If the request
contains ga:cohortNthDay it should be exactly one day long, if
ga:cohortNthWeek it should be aligned to the week boundary (starting at
Sunday and ending Saturday), and for ga:cohortNthMonth the date range
should be aligned to the month (starting at the first and ending on the
last day of the month). For LTV requests there are no such restrictions.
You do not need to supply a date range for the reportsRequest.dateRanges
field.
