How many months can someone travel to still be considered a domestic tourist?

The definition of a domestic tourist typically doesn’t depend on the duration of travel but rather on the destination relative to the traveler's home country. Generally, a person is considered a domestic tourist as long as they are traveling within their home country, regardless of the number of months spent traveling. Therefore, one could travel for several months and still be considered a domestic tourist as long as they remain within the borders of their home country.
