Today a weird guy with a pointy hat offered me and my friends to play a game: We will all travel back in time, to a random date somewhen from the antiquity to modern times. We will have a limited amount of time to do whatever we want before returning to our current world. After that time, each of us tries to guess the date we travelled to and the winner is the one who comes closest to the real date they travelled to.
- It's not time travel per se, but more a kind of simulation, so interaction in the past won't have impact on the present.
- We will all travel to the same time period, but we will not be able to interact with each other.
- We will stay more or less in the same area, i.e. western Europe. Sometimes in the middle of a forest, sometimes inside a city, but always western Europe.
- Each of us are fluent in French, and know some basics of English, Spanish and German. Local people will speak the language that was spoken during their time period in their specific region.
- We are not historians, and even subjects to some TV-tropes and other cliches.
- We can't bring any device with us, like a computer or astronomical tools.
- The amount of time before we come back to the current time period is unknown to us, but always between 5 minutes and 5 days. Ideally, I would like a method to do a rough estimation, and narrow it more and more untill I came back to modern times.
- If you die in the simulation, you go back to the present. Being killed have no impact on current time, but is still good to avoid as you can feel pain and you will have less time than others to estimate on what period you landed
- We have no time to prepare ourself: the wizard just give us few minutes so we can decide if we want to play, but no time to learn greek or do a PHD in history. I can do a quick google research like translate a phrase in latin, but nothing that take more than a minute.
- Estimation such as "X year of reign of dude Y" are accepted if it's the contemporary way to count years
- You have to answer immediately after you get back
This might be seen as a duplicate of the question My time machine needs to know when it is at first, but that question focuses on tools and science (astronomy, carbon dating...) to have an exact dating, while my question focuses on estimation using no tools, interacting with local folks, trying to evaluate technological advance, studying architecture...
How could I know when I landed?
