Not on the calendar though.
Well, the 25th is the festival of the Sol Invictus. So, if anything, it was at least until yesterday. Whether it was really prolonged until then or not, it's debatable. I think the 25th may be related to Khepri or Azazel. Most likely Khepri since he is not only a solar God as Azazel, but also patron of soldiers like Mitra, to whom the Sol Invictus holiday was dedicated to.
