Need standard validations for Start and End Dates. Should include:

1. End Date > Start Date.
2. End Date < Today Date.
3. Start Date < End Date

So far tried below approaches, but these do not work completely:

Edit

[HttpPost]
        public IActionResult Time(Time modeo)
        {
            if (ModelState.IsValid)
            {
                // add your code here.....
                
                
            }
            //return model and error message
           return View(modeo);
        }
