Best time to start a business, for your chart

Traditional electional astrology says to start a business when the Moon is waxing, Mercury and Venus are moving forward, the Moon is not void of course for long and no eclipse is within a week. This calculator applies those rules to each of the next 90 days, then adds your own chart: it favours days when the Moon is in your 10th, 2nd, 1st or 11th house and avoids the 6th, 8th and 12th.

The next 90 days graded by the old rules for beginnings, then matched to your own chart, with the reasons for each day.

How it is calculated

The sky layer uses the same day-by-day table as Shymea's best days to start a business calendars: Mercury, Venus and Mars retrograde and shadow periods, the Moon's phase and sign at 12:00 UTC, the void-of-course Moon and the distance to the nearest eclipse, all precomputed from NASA JPL's DE442 ephemeris with Skyfield. Each day is graded best, good, fair or wait by the same rules.

The personal layer uses your rising sign from the Shymea engine, or your Sun sign if you don't know your birth time, and counts the Moon's sign that day as a whole-sign house from it. Days graded best or good with the Moon outside your 6th, 8th and 12th houses pass; the six strongest are listed.

Common questions

What is the best day to start a business astrologically?
By the traditional rules, a day with the Moon waxing, Mercury and Venus direct, little void-of-course time and no eclipse nearby. Personalised, astrologers also prefer the Moon in your 10th, 2nd, 1st or 11th house. The calculator lists the days that meet both.
Should I avoid launching during Mercury retrograde?
Traditional electional astrology says yes for contracts and launches, and the calculator marks those days as wait. If your launch date is fixed, astrologers suggest double-checking paperwork rather than cancelling.
Do I need my birth time?
No, but it helps. With a time the houses are counted from your rising sign; without one, from your Sun sign, which is less personal.
Does the time of day matter?
In full electional astrology, yes: the chart for the launch minute is read too. This calculator works at the level of days. For the hour, astrologers also avoid the times when the Moon is void of course.

Sky conditions are precomputed day by day with Skyfield on NASA JPL DE442 (tropical zodiac, UTC days, Moon sign at 12:00 UTC) and graded with the same rules as the best-days calendars. Your rising or Sun sign comes from the Shymea engine. The house preferences are an electional convention, not a calculation. Readings are educational, not medical, legal or financial advice.
