Why the date matters for time-zone conversion
Central Standard Time is associated with a region whose local clock can change seasonally. For that reason, the UTC offset used for a conversion to IST is not necessarily identical on every date. The calculator uses the selected date and the underlying IANA time zone to determine the applicable local-time offset.

How this time-zone converter works
The converter uses named time zones rather than relying on a single fixed hour offset. That matters because some locations change their clocks during part of the year while others do not. Selecting the actual date lets the browser calculate the local-time representation for that date.
