  • Well, when the loop takes place there is a travel in time taking place… but not as in the standard time travel films.

    I think is important to point out that in the Groundhog time loops the travel is only of the memories or the information, there is no energy-mass traveling (though information is a kind of energy, let me skip physics here), and the traveler at the beginning of the loop has not carried anything from the future but the memories of the previous loop, did not age or suffered physical modifications (there may be exceptions, sure).

    So I think that is a kind of time travel, but a sub-genre where the travel is less material than in the typical time travels.

  • The question is whether a time loop is a form of time travel.

    Are they actually going back in time? Or is time itself looping back on itself? These aren't the same cause, though the effects can look the same

    So I suppose, conventionally, it can be thought of as a subform of time travel. But from a technical perspective, it may or may not be

  • I mean, time-travel stories typically involve traveling by way of some mechanism be it a spell, wormhole, tear in spacetime and etc. The end goal is usually traveling from one point to another with a purpose. Characters can travel back and forth. Everyone usually remembers each encounter.

    Time-loops, like in Groundhog's Day or Edge of Tomorrow, usually cause people to get "stuck." Some plot device is then introduced to eventually "unstick" them. Only the people stuck in the loop are usually aware that anything is happening.
