Tomorrow marks the Kalends of April, the first day of the month. In Ancient Rome, this was the day that state-sanctioned sacrifices were made to Juno, Janus, and the Lares. The date of the Nones, the day all other monthly festivals were publicly announced, was given. While a few syncretic Roman Revivalists follow the lunar cycle of marking the Kalends, which would be when the first sliver of a new moon could be seen in the sky or (not quite as accurately) the new moon, most of us observe the first of the month as the Kalends. That was how it was marked for the majority of Rome's history.
Most months, I work extra hard to make sure that I cook a modest but well-balanced meal for my family from scratch on this day. We offer at the lararium, or shrine to the Lares and household Gods, that sits in the middle of our dining room table. In my home, we bring the Gods to the table with us when we eat. We offer the first bites of food from our plate to the Lares, giving Them what They are due, along with all food that might happen to fall onto the floor. With a toddler in our house, the Lares get fed well with all the food that falls.
The rest of the religious duties of the day fall on me, though, and that's because I'm technically the only person in the house of this religion.
Except this is going to change this month. It was agreed upon many years ago that any child I had would be raised within my religion, since my husband is an agnostic humanist who loves Christmas. Now at 3-years-old, I feel like my daughter has hit that magical age where she's ready to start really learning about the Gods (though she continues to insist there are only 2 Gods) and participate in her mother's religion.
