Description	AR Aurigae is an often observed detached eclipsing binary which can serve as a laboratory for various techniques for the time minima determination. We present a rigorous method of light curves extrema determination and compare it with the standard Kwee-van Voerden method. We discuss also causes of the discrepancies among various estimates the uncertainty of the time extrema determination and real scatter of OC values.
