How to get the count down time in different items (MVC )

Follow below steps:

Step 1: Add two columns StartAuction and EndAuction which will store auction start data and end date. Super admin needs to set the value to these columns.

Step 2: Once auction start and end date is set and user is viewing an item then fetch both column's value(start auction and end auction date). After getting fetch convert the value to DateTime object using javascript. And then do minus operation from auction end date with today date timw. It will shows how many hours it is remaining.
