A game is free from Monday until Wednesday, meaning the game will no longer be for free after midnight on Wednesday (Wednesday 23:59).
It is around afternoon Monday and my friend asks me for how many days will the game still be free to play?
Should I respond for 2 more days or 3 more days?
2 more days meaning (Tuesday + Wednesday)
3 more days meaning (today + Tuesday + Wednesday)
I am not sure that if something is already happening whether I should count that in or not.
But I would go for three days because you can play it still today + 2 extra days.
How is "for n more days" understood? Do people use it meaning as extra days not counting today, or still including today?
