The biggest thing is our midwinter feast for the Solstice, which we're having on June 20. I'll do my own Solstice rite on the 21st, since my parents will be away overnight and I'll have the house to myself. Other than that, it's my normal set of daily and monthly devotions. I'm adding Isis to the mix this month, because I want to get back into the habit of working with Her, so I'll just stick with simple offering rites for now, and see where that goes. I feel it's been too long since I last did ritual to Her.
I'm looking at old festivals and holidays while building my personal spiritual calendar, and I came across Panathenaea, a festival celebrated in honor of Athena every four years on June 8th. The ancients seemed to celebrate it with physical contests, but for my personal use I'm going to try it this year with games of mental skill, like chess.
I'm also going to make a post about the visit my husband and I made to Nashville's Parthenon last year, and make a plan to make a pilgrimage of it every four years.
For the past couple of months I've been keeping up with Deipnon and Noumenia, and am trying to incorporate more offerings and prayer on weekends in addition to my (often shorter than I'd like) nightly prayers. I also would really like to start working on some kind of calendar, since I've never used one before, but that is going to take longer than the span of a month to work on, I think.
