Mercurial Corrections
One the course of — more than — two dozen years, I’ve employed a number of formats. In the early years, I used an ephemeris to get the exact dates for that one year, when the Sun would shift signs.
The American Ephemeris for the 20th Century 1900 to 2000 at Noon
The year I pulled from, though, was leap-year, or an off-year — or something. I don’t know; see the
fineprint for details and disclaimers.
I carried that data forward for more than two years, as an existing format, the days, the dates, for each sign. I consider those dates as guidelines, as the typical ephemerides, usually, are set for GMT. As noted, your mileage may vary.
What I learned from my mistake?
How it varies, and not to put the exact dates in print form. Depends on location on the planet and time of day, time zone, and so forth.
All depends. I got used to using a computerized version of chart-making, first a program, then an app, and like I’ve suggested, maybe my watch can calculate an astrology chart now, but I can’t be bothered as the data isn’t
that important.
Using those digital placeholders and format, though for a couple of year, it educated both me and some others, about not even putting data in the horoscopes. These days, I use a local time, not Eastern Standard, or West Coast. Just Central. Works for me. Wait, there’s that Daylight Savings thing, too.
A retrograde Mercury was a perfect time to comb through the database and correct a minor point about formatting with those early horoscopes. 123 entries, in all. Two years, early years. Touched up.

I left the dates and data the way it was. Still, it is cleaned up.
