Translation:The period goes from October to December.
I am not a native English speaker but shouldn't "The period lasts from October to December" be correct as well?
Yes, that's right. As a native English speaker, I think your suggestion is more natural than this one.
I am also a native English speaker, but I'd find it more natural to say 'goes' here. Both are technically correct, I think dialect determines the preference.
So earlier, Duolingo told me that går refers specifically to walking and not to going, but now here it's used for an abstract going. The language used in the help text could be made more specific.
Is there a particular reason why "The period is from October until December" is wrong? Seems like the same thing as "The period goes from..." which sounds kind of weird.
I have just been marked wrong for saying 'October til December'. I am told it should be 'October till December'. This is incorrect as the "til" used in British English is a shortened version of "until". Till is to turn the soil or a place to keep money in a shop, and NOT to be used in place of "til'. I am angry - can you tell?
