Leo Season End Dates: What You Actually Need to Know
Leo season runs from roughly July 23 through August 22 or 23 each year. The exact end date shifts because the sun doesn't move on a calendar — it moves on its own schedule. Astronomically, Leo season ends when the sun crosses the celestial sphere boundary from the constellation Leo into Virgo. That moment is called solar ingress, and it typically happens between 10am and 4pm ET, though the exact time changes every year. Here are the specific dates for the next few years. 2024: August 22 at approximately 1:38pm UTC. 2025: August 22 around 7:53am UTC. 2026: August 22 or 23 depending on your timezone. If you're checking for a specific birth chart or an event you're tracking, you need the exact minute, not just the date. That 24-hour window shift is where people get tripped up. I run a small astrology newsletter and spent two summers dealing with readers who blamed the wrong sign for whatever was happening in their charts. Someone had a birthday on August 22 at 11pm in Chicago. Depending on whether you use tropical or sidereal calculations and which timezone your software defaults to, they might be getting a Leo reading or a Virgo reading. I stopped trying to explain it and just started asking for the exact birth time and location, then running it through a few different ephemeris sources to confirm. The workaround that actually works is cross-referencing timeanddate.com's solar ingress data with a proper sidereal wheel. They rarely disagree by more than a few minutes, which matters if someone's planet is conjunct the critical degree.
How to Check the Exact End Time Yourself
The most straightforward approach is timeanddate.com's Sun in Each Zodiac Sign page. They list ingress times in UTC and your local timezone. The data comes from Swiss Ephemeris calculations, which is the same source most professional astrology software uses. Another option is Astro.com's free ephemeris download or their "Extended Chart Selection" tool where you can plug in any date and see the exact solar position. If you want to go deeper, JPL Horizons gives you ephemeris data for the sun at any historical or future moment. It's a NASA database, raw output, no pretty charts, but the numbers are authoritative. I use it when someone sends me a questionable chart and I need to verify whether a planet was actually in Leo or already in Virgo at the time of birth. Takes about 30 seconds if you know what you're doing.
Common Mistakes People Make
Using the cusp dates as fixed boundaries. Leo season doesn't start on July 23 at midnight and end on August 22 at midnight. It starts and ends at whatever moment the sun hits 0 degrees of the respective sign. That can be any hour of the day. Also, the calendar drifts. Over decades the dates slide by a day because the tropical year is about 365.2422 days, not 365. Leap years catch most of it but not all of it. Another thing: people assume everyone switches signs on the same day. Timezone matters. If the ingress happens at 11pm UTC on August 22, that's still August 22 in London but August 23 in New York. Birth charts are timezone-specific. Event charts are timezone-specific. If you're casting a chart for something happening during that transition window, pick the right timezone or the whole thing is wrong. The big limitation with all of this is that astrology itself doesn't have a governing body that standardizes anything. Different traditions use different starting points. Tropical astrology, which almost all Western astrology uses, is based on solstices and equinoxes, not actual constellation positions. Sidereal astrology uses the fixed stars and is off by about 24 degrees right now due to precession. If someone tells you the sun is in Leo when it's actually September, they might be using sidereal. Know which system you're working with before you trust the output.

What Changes When Leo Season Ends
People who track transits notice the shift because the ruler of the season changes. Leo is ruled by the sun. Virgo is ruled by Mercury. The solar transits that dominated July and early August drop out, and Mercury movements become the primary driver. That means communication, routine, health routines, and detailed work become more prominent in transit-based interpretations. It's not dramatic. The sun doesn't vanish. But if you're watching for specific solar aspects to natal planets, those aspects pause until next summer. The practical takeaway is this: Leo season ends when the sun hits 0 degrees Virgo, usually August 22, sometimes August 23. Check the exact time for your purposes. Use a reliable source. Don't assume the calendar date is fixed. And if your chart seems off during that transition period, timezone or system difference is the first thing to check before anything else.
