257,885,161 -1 as of 2013. New primes are being calculated all the time, so this will change as new and larger ones are discovered. Also, note that there are infinitely many primes (proved by Euclid around 300 BCE), so there won't ever be a single "highest" prime, only the highest one known.
The largest known prime number was discovered in August 2008.It has about 12.9 million digits - so we won't be reproducing it here!It is one less than 2 raised to the 43112609th power:243112609_-1" Other primes have been found since then but they are smaller numbers.

To determine the number of days until September 1, 2010, you would need to know the current date. Since today is after September 1, 2010, it is impossible to calculate the number of days until that date as it is in the past. If you meant a future date, please provide clarification.
