Generally speaking, the word order in English sentences tends to be pretty strict and less flexible than, for example in Spanish.
This is why you should remember that adverbs of time (yesterday, today, in three weeks, two days ago, tomorrow, for three days, since October….) are almost always placed at the end of a sentence:
I’ll see him tomorrow.
She went to China yesterday.
They have been married for ten years.
I’d like to see you now.
Most of these adverbs of time, may sometimes be placed at the beginning of the sentence, though this is not so common:
Yesterday I saw a very good film.
Tomorrow we’ll fly to New York.
The adverb of time just, which is used with the present perfect tense has to be placed after the auxiliary verb have/has, never at the end of the sentence:
She has just left the office.
They have just finished the meeting
PLease notice that the adverbs of frequency are also places between the subject and the verb:
I often listne to music in the evening.
However, when we have a modal verb (to be, can, could, must, should, will..) the adverbs of frequency are usually put behind them:
She is always late.
