Held in late Mounichion/early Thargelion known only from two entries in the Lycurgan skin-sale records (Parker, Polytheism 473). The epithet Hegemonius likely refers to a role played by the god in leadership, victory and/or expansion (Radulovic et al, Transformer). I'm guessing that it is on Thargelion 4 (May 2 in 2025) because the fourth is the day of the Attic month to honor Hermes
