Again... assumptions galore.

I can tell you what I saw... and what I didn't see.

1. Chara was wearing a sweater. Which means sweaters existed when they fell. So we can rule out a time before the 20th century (assuming that world's fashion evolved like ours, which is, again, a big assumption).

2. Monsters emerged to the sunlight and a patch of grass, but that is pretty much all we can see of the scenery they met when they crossed the barrier. In the ending credits, we see a city and a beach, but there's no way to know how close/far to Mt. Ebott they are. There is no way to tell whether any of that was once Chara's village or not.

3. How can you tell that guide dogs will not be used in the future? Why wouldn't they? Or what types of cars will be used 100 years from now? As for the trash, some of it is pretty timeless and some is already very old (look at Napstablook's TV set, for instance). And most of it we only see as amorphous blobs. So we can't really tell the time by the trash we get to see.

4. We do know, however, that Toriel had a cellphone (albeit an old one). And the monsters in the Ruins seemed to be out of touch with the rest of the world, so I'd say that either she got her cellphone from one of the humans who fell into the Underground, or she already had it before she left New Home. If it's the latter, then the story must take place in the future (or in a world with a different history of technological development).

5. As for the calendar, I'm not Christian and I use it too, just because it's the official calendar where I live. Most peeople don't see it as a religious calendar at all, it's just the way years are counted. Monsters may have continued to count the years in the same way they did before - which probably didn't match our current calendar anyway because this calendar was not in use 2000 years ago -, or started their own calendar. And considering they've been trapped for at least 2000 years ("thousands of years of imprisonment") and Chara fell down in 201X, the latter sounds more plausible. That is informative regarding how long monsters have been trapped, but it doesn't tell us anything about the date in the human calendar, so we're left with little solid ground for our theories. All we can do is speculate. And that is if that world even has a chronology similar to our own, which is also anyone's guess.
