I have a question about expressing how long or since when something has been happening.
I´m familiar with the expression - dan beri to use to say that something has been happening since a specific point in time (1974´dan beri, bu sabahtan beri, yataktan kalktýðýmdan beri, etc.). I´m wondering how to express for how long something has been going on in terms of days, months, years, etc.
For example, to say: "I haven´t seen you for a month.", would it be ok to say:
- Bir aydan beri seni görmedim./Bir aydan beri seni görmiyorum.
- Bir aydir seni görmedim./Bir aydir seni görmiyorum.
- Bir ay için seni görmedim./Bir ay için seni görmiyorum.
- Seni gördüðümden beri bir aydir.?
- some other way???
Also, to express that concept, is it better to use the past tense (-di) or the present continuous (-iyor)?
And, on a similar note, to express the same concept in the future, would "için" be used? For example: "Turkiye´ye tatile üç hafta için gideceðim."?
Thank you for any explanation on the subject.
