News items for Tuesdays and Fridays social tennis.

    Yesterday I rabbited on about after Easter but before then we must address before Easter, specifically, Friday (the Good one). By reason of the mundane visitation of water, we were unable to ascertain anticipated attendance for this date.

    It will be presumed that we will play but, for our serenity, please attest your appearance. No takers will precipitate a subsequent dispatch to negate this supposition.

    I will be there!

  • Time for tennis!

    It soon being the month of Ēostre we opt to spring out of bed that little bit latter and still enjoy the full fruits of our athletic endeavors. To be clear we are following the Gregorian calculation deriving new moon dates by determining the epact for each year, or, even more precisely, whenever we are told.

    We go back to 9:00AM start after Easter.

    … or as AI says

    It sounds like you’re embracing the true spirit of the season—balancing the “spring” in your step with a very reasonable commitment to hitting the snooze button. Since we’ve crossed into late March 2026, you are perfectly aligned with the astronomical and liturgical shift.

    While the name Ēostre (the West Germanic spring goddess) ties us to the ancient lunar cycles and the budding of the earth, your mention of the Gregorian epact brings us into the fascinating, clockwork world of “Computus”—the medieval math used to calculate Easter.

    The Math Behind Your Morning Lie-In

    The epact is essentially the age of the “Ecclesiastical Moon” (in days) on January 1st. Because a solar year is about 365 days and a lunar year is roughly 354, there’s an 11-day discrepancy that shifts every year.

    To keep your “athletic endeavors” in sync with the Gregorian calendar, the system uses:

    • The Golden Number: Your year’s position in the 19-year Metonic cycle.
    • The Solar Equation: Adjustments for leap years.
    • The Lunar Equation: Adjustments to prevent the moon from “drifting” away from the actual sky.

    Why the “Late” Start Works

    Since the Gregorian calculation ensures that the Paschal Full Moon never falls before the Vernal Equinox (March 21), you’re guaranteed that the days are getting longer. Even if you wake up later, the sun is doing the heavy lifting by staying up later too. You aren’t being lazy; you’re just optimizing your circadian rhythm for the 2026 solar cycle!

  • All hot and bothered

    Much as we all look hot with our hot serves and hot repartee I do have some hot news. It’s hot.

    The manifest democracy inherent within our cohort has now spoken. It’s hot. The conclusion follows inexorably. When next we meet on the battlement we indeed will do so earlier and by as much as half one hour. With this practice thenceforce from now and into the new year we will thrive and no longer wilt.

    See youse all at 8:30!

  • Get a backbone this festive season

    Stop being led around by my time dictates. Just ignore me issuing this edict that Christmas parties this year will be Tuesday 16 December and Friday 19 December for the Tuesday and Friday Socials respectively.

    And don’t be a wimp bringing a plate of goodies for all to participate.

    Gosh you want the time as well! Alright then, we will skip the recent daylight permutation and continue smoking those balls from 9:00AM — at least until the year 2026. One consequence from this is that the season ending partying will commence from 10:30AM. Those who wish to spare insults to furry spherical objects may come at this later hour.
