Toriel is aware that Anime Isn’t Real.

If it was the 24th century, it would be.

Gaster’s secret weapon is that he comes from a world where Anime IS real.

A world different from the surface above Undertale. Which seems very similar to our own modern-day Earth.

You can see what typical monster technology was like before Gaster, in rustic Snowdin.

It’s only when you go to the Core, and the lab behind Sans’ house, that everything goes futuristic and bizarre.

The human world on the surface has modern 21st century technology.

The time is the modern era.

And there is no evidence that the Monster Calendar is different from the human one.
