Sky Calendar 2026 in Tennessee
Every dated sky event of the year, with sunset, moonrise and hours of real darkness worked out for Nashville. The dates are the same everywhere. What happens on the night is not.

Every clock time on this page is the Naval Observatory's own answer for Nashville, read for that exact calendar date on that city's clock rather than interpolated from a national figure.
How dark it actually gets in Tennessee
Tennessee sits in the middle of the country's darkness range, with 5h 42m of true astronomical darkness at Nashville on the June solstice and 11h 14m on the December one. Summer peaks are workable and winter peaks are generous, so which shower is worth the drive comes down to the moon rather than the season. The darkest sky the state has easy access to is Pickett CCC Memorial State Park, which is where the faint half of this calendar is actually worth chasing.
Sunset is not darkness. After the sun goes down the sky keeps giving off light for well over an hour, and the point at which it stops, and faint things become visible, is when the sun is more than eighteen degrees below the horizon. How long that lasts is a function of latitude and time of year, and it is the single biggest difference between one state’s night and another’s.
Astronomical darkness means the sun is more than 18 degrees below the horizon at Nashville, which is when the sky stops contributing any light of its own. This figure is computed by MyWild, not published by USNO: the Naval Observatory’s daily tables carry civil twilight, which is the sun only 6 degrees down and a good deal brighter.

That spread is why the same meteor shower is a different proposition in Tennessee than it is three states away. A shower that peaks in June has a short window to work with here and one that peaks in December has hours. The table below applies the state's own numbers to every peak of the year.
The best meteor night in Tennessee this year is the Geminids
On the night of December 13 the sun sets at 16:33 at Nashville, the sky goes properly dark for 11h 13m, and the moon leaves about 76 percent of that alone. Against a shower that can reach around 150 an hour from a dark site, that is the combination worth driving for.
| Shower | Peak night | Sunset | Dark for | Moon lit | Moon free | Verdict |
|---|---|---|---|---|---|---|
| Quadrantids | Jan 3 | 4:45 PM | 11h 10m | 100% | 0h 00m | Poor, the moon is up for nearly all of it |
| Lyrids | Apr 22 | 7:27 PM | 7h 30m | 35% | 1h 59m | Fair, the moon takes a good part of the night |
| Eta Aquariids | May 5 | 7:38 PM | 6h 55m | 86% | 0h 00m | Poor, the moon is up for nearly all of it |
| Perseids | Aug 12 | 7:41 PM | 7h 12m | 0% | 7h 12m | Excellent, the moon is near new |
| Draconids | Oct 8 | 6:21 PM | 9h 38m | 4% | 9h 38m | Excellent, the moon is near new |
| Orionids | Oct 21 | 6:03 PM | 10h 05m | 78% | 0h 16m | Poor, the moon is up for nearly all of it |
| Taurids (Southern and Northern) | Nov 5 | 4:47 PM | 10h 33m | 13% | 9h 24m | Excellent, the moon is out of the way |
| Leonids | Nov 17 | 4:38 PM | 10h 51m | 53% | 5h 04m | Fair, the moon takes a good part of the night |
| Geminids | Dec 13 | 4:33 PM | 11h 13m | 19% | 8h 33m | Good, most of the dark window is moon free |
| Ursids | Dec 22 | 4:37 PM | 11h 14m | 97% | 0h 00m | Poor, the moon is up for nearly all of it |
Moon lit is the illuminated fraction USNO publishes for that night. Moon free is the part of the dark window with the moon below the horizon, which matters more than the phase: a bright moon that sets at eleven costs you nothing after eleven. For tonight rather than the year, use the meteor shower tonight page, which adds cloud cover.
2 of 2026's eclipses reach Tennessee
Visibility here is not read off a map. For a solar eclipse it is the Naval Observatory’s own answer to a query at Nashville’s coordinates, and an eclipse it calls not visible from there is not visible from there. For a lunar eclipse it is whether the moon is above the horizon at Nashville at the instant of greatest eclipse, from USNO moonrise and moonset against NASA’s contact time.

Looking at a partial solar eclipse will damage your eyes. There is no moment during a partial eclipse when it is safe to look without a certified solar filter, and sunglasses, exposed film and smoked glass are not filters. A pinhole projector costs nothing and is entirely safe. A lunar eclipse is different and needs nothing at all.

- Meteor shower tonight answers whether a shower is running right now, with cloud cover. This page answers when the next one peaks.
- Stargazing forecast tonight answers whether tonight is worth going out at all.
- Milky Way season in Tennessee is the dark sky season rather than a dated event: which months the core is up over Tennessee and how dark it needs to be.
- Northern lights forecast is space weather, which has no dates at all and is the one sky event nobody can put on a calendar.
Tennessee's dark sky reference on this site is Pickett CCC Memorial State Park, and the Milky Way season page for Tennessee carries the months and the nightly windows for the one thing on this calendar that genuinely needs a dark sky rather than just a clear one.
