Anniversary of the Martyrdom of Polycarp

I forgot that 23 Feb is the traditional day for celebrating the anniversary of the Martyrdom of Polycarp.

Then, the proconsul urged him, and saying, “Swear, and I will set you free, curseChrist;” Polycarp responded, “Eighty and six years have I served Him, and He never did me any wrong: how then can I blaspheme my King and my Savior?”
M.Pol. 9.3
