As they say, this isn't even wrong... you have been told umpteen times that there are 366.25+ sidereal days in a year, because sidereal days are 4 or so minutes shorter than day/night cycle solar days. This necessarily means that each non-circumpolar star rises 366 times a year... which seems to indicate that such a star, on one particular day, must rise twice! I can hear you screaming from here that this is impossible.
... and you will find a page that calculates the rise/set/transit times for major solar system bodies and bright stars. You can pick any major location in the USA, along with several US territories, pick a month, pick a date, and pick the object in question. I live near San Diego, for instance, so type in my city, state of California, choose October 1st of 2011 and '31' for Number of Days. I used '10' for altitude, but it doesn't matter much.
When you click 'compute data' you will get a read-out for the entire month of October. Scroll down to October 25th, and what do we find? Why lookie here, on this date Sirius rises at 3 minutes after midnight and again at 23:59 the very same day. Funny thing, there is 23:56:04 between risings... just exactly what the definition of a sidereal day tells us! It must be a miracle, or perhaps it is a dirty rotten lie, I dunno.
While you are at it, go back a request the same information for June, where you will see that Sirius rises at about 9:47 in the morning on June 1st and slowly moves to rising at 7:39 in the morning by the end of the month. Just because you can't see it rise with your nekked eye doesn't mean it is not in the sky, no matter how hard you don't want it to be true.
You can even set the page for January 1st and select 365 days, and get the rise times for the entire year, all 365 days, and see for yourself just how those rise times fall back each day by those same 3 minutes and 56 seconds each day.
This really isn't so hard, if you would only remove your cranial calculator from its rectal storage facility and try, try, try to actually learn something that you clearly don't understand now.
