The date input to validate. Can be a number, Date object, or string.
true if the input is a valid date input, otherwise false.isValidDate(1639939200); // true (valid Unix timestamp)
isValidDate(new Date()); // true
isValidDate("12/31/2023"); // true
isValidDate("01-01-2024"); // true
isValidDate("2024-01-01"); // true
isValidDate("Aug 11, 2025"); // true
isValidDate("August 11, 2025"); // true
isValidDate("12/31-2023"); // false (inconsistent separators)
isValidDate("31/02/2021"); // false (invalid date)
isValidDate("2022"); // false (just the year, invalid date)
isValidDate(""); // false
isValidDate("INVALID DATE"); // false
Interim implementation that simply proxies to parseDateInput. Validates whether the provided input is an acceptable Tremendous date input. Accepts numbers (as Unix timestamps in seconds),
Dateobjects, and date strings in"MM/DD/YYYY","MM-DD-YYYY","YYYY-MM-DD","YYYY/MM/DD","MMM DD, YYYY", or"MMMM DD, YYYY"formats with consistent separators. The function checks for correct format and basic date validity. If this function returns true, it means the date is serializable.
