I think the function toLocaleDateString use the default local data on the device.
try this code to check the output:
// America/Los_Angeles for the US
// US English uses month-day-year order
console.log(date.toLocaleDateString('en-US'));
// → "12/19/2012"
// British English uses day-month-year order
console.log(date.toLocaleDateString('en-GB'));
// → "20/12/2012"
// Korean uses year-month-day order
console.log(date.toLocaleDateString('ko-KR'));
// → "2012. 12. 20."
// Arabic in most Arabic speaking countries uses real Arabic digits
console.log(date.toLocaleDateString('ar-EG'));
// → "٢٠/١٢/٢٠١٢"
// chinese
console.log(date.toLocaleDateString('zh-Hans-CN'));
// → "2012/12/20"

JavaScript Date toLocaleString() This method formats a date into a string, using language specific format.
Examples :
Only date :
var n = new Date();
console.log("es-CL: " + n.toLocaleDateString("es-CL"));
// es-CL: 03-09-2021
Date with Time :
var n = new Date();
console.log("es-CL: " + n.toLocaleString("es-CL"));
// es-CL: 03-09-2021 17:56:58
