If star fragments come the day after you wish on the stars, do they despawn the after the day they spawn. Because yesterday I wished on many stars, but don't have time to play today and am worrying if my star fragments will be gone tomorrow.

The one time I got star fragments I just time travelled to the next morning to pick them up. You can do the same if you just rewind the time to 'this morning' when you want to pick them up, then synchronize it to the internet afterwards.
I know it's not a direct answer to your question but it is a solution and it's a valid thing to do if you simply cannot play on the day you were due to receive the fragments.
