Individually, these two are totally fine JSON strings.

[{"`19 January 2021`":[["36","817","67"]]}]
[{"`20 January 2021`":[["79"]]}]

You can't parse them both together at the same time just by concatenating them though. Either parse them individually:

JSON.parse(arr1String);
JSON.parse(arr2String);

Or combine them into a single JSON object.

echo json_encode([
    "arr1" => $arr1,
    "arr2" => $arr2
]);
