¿The epoch time calculated in Keplerian Elements is a Julian date or is a Gregorian date?. I think than is a Greogorian date, but I am not sure.

I understand your confusion. The date is specified using the Gregorian calendar. The Julian calendar is obsolete.

Dates used in astronomical calculations are often referred to as "Julian Dates", but this does not refer to the Julian calendar. Instead, this simply means a number that indicates the number of days since some agreed-upon time.
