It depends on what speed you are going at. Assuming you are in our fastest spacecraft as of now which has a speed of 17,500 mph
1 light second = 186,282 mph
There are 31,536,000 in one year so 17,500x=31,534,000 and your answer would be in years. It would take you roughly 1802 years.
(Sorry about mph I'm American.)
