If the data is not aggregated at a daily level, an event could also be shared at a week, month, year level as well by just defining a startDate and endDate. Not the startDate and endDate should cleanly fall in a week, month, year, last 7 days, last 15 days or last 30 days.

{
    "startDate": "2019-01-01",
    "endDate": "2019-02-01",
    "grade": 1,
    "school_id": 901,
    "count": 23
}

if you cannot guarantee this, it would be better to use an alternative API to push an event as below.

{
    "week": "2019-W21", // or "month": "2019-M11" or "year": "2022"
    "grade": 1,
    "school_id": 901,
    "count": 23
}
