Thanks for the answer. So I should calculate 2 values (1 for each year), but is it better to do this using the 502 daily returns or using the 503 daily values of the stock (I forgot to precise that I have this data)

Stock return is $(p_{t+1} - p_t +d)/p_t$ where $p$ is stock price and $d$ dividend (if there is any), if you want a return for a year for a daily data you can use $(p_{365} - p_1 +d)/p_1$. People often do average yearly returns, where you just average all returns throughout the year, but that wasn't in your question.
