Dear Calendar People:
Of special note to CALNDR members is the new support of symmetrical leap cycles within the Symmetry454 calendar and its variants, for fixed arithmetic cycles.
For the preferred 52/293 leap cycle, this means that in the leap rule K=166 is changed to 146 in this beta. This will soon become the calendar's new leap rule -- more than 5 years after Karl Palmen first suggested it! (I'm still polishing off PDF documentation revisions, not changed at Sym454 home page yet.)
The Previous and Next menus now have commands to jump to the previous or next leap cycle. Press Ctrl-A to do it again, repeatedly, to quickly check astronomical drift into the past or future, watching the solar longitude, starting from the desired point in the first year of a leap cycle, such as the day corresponding to the calendar season of the leap cycle.
The Symmetry454 leap year lists now show the symmetrical subcycle groupings.
