RangeError: invalid date
The JavaScript exception "invalid date" occurs when an invalid date is attempted to be converted to an ISO date string.
Message
RangeError: Invalid time value (V8-based) RangeError: invalid date (Firefox) RangeError: Invalid Date (Safari)
Error type
RangeError
What went wrong?
You are converting an invalid date value to an ISO date string by calling the toISOString() method.
An invalid date is produced when you attempt to parse an invalid date string, or set the timestamp to an out-of-bounds value. Invalid dates usually cause all date methods to return NaN or other special values. However, such dates do not have valid ISO string representations, so an error is thrown when you attempt to do so.
Note:
toJSON() does not throw this error. It checks whether the date is finite before formatting it, and returns null for an invalid date instead of calling toISOString(). JSON.stringify(), which calls toJSON(), therefore serializes an invalid date as null rather than throwing.
Examples
Invalid cases
const invalid = new Date("nothing");
invalid.toISOString(); // RangeError: invalid date
However, most other methods return special values:
invalid.toString(); // "Invalid Date"
invalid.getDate(); // NaN
invalid.toJSON(); // null
JSON.stringify({ date: invalid }); // '{"date":null}'
For more details, see the Date.parse() documentation.
Valid cases
new Date("05 October 2011 14:48 UTC").toISOString(); // "2011-10-05T14:48:00.000Z"
new Date(1317826080).toISOString(); // "2011-10-05T14:48:00.000Z"
