Key Holidays and Observances in July 2024
July 2024 is packed with national holidays, international observances, and cultural milestones. The most prominent include:
- July 4, 2024: Independence Day (United States) — Celebrated with fireworks, parades, and barbecues across all 50 states. This date also marks the 970th anniversary of the Crab Supernova (SN 1054), observed by Chinese astronomers during the Song dynasty, which created the Crab Nebula (M1).
- July 4, 2024: UK General Election — The Labour Party, led by Keir Starmer, won a landslide victory with 412 seats, ending 14 years of Conservative rule. The Conservatives secured only 121 seats.
- July 14, 2024: Bastille Day (France) — The national day of France, commemorating the storming of the Bastille in 1789. In 2024, this coincided with the UEFA Euro 2024 final, where Spain defeated England 2-1.

- Plastic Free July — A global challenge started in 2011 by the Plastic Free July initiative, encouraging individuals to avoid single-use plastics for the entire month.
Astronomical Events: Moon Phases, Planetary Oppositions, and Aphelion
July 2024 is a rich month for skywatchers, with multiple planetary oppositions, a key lunar phase cycle, and Earth’s farthest point from the Sun.
Moon Phases for July 2024
All four primary moon phases occur in July 2024, with specific astronomical significance tied to each:
- New Moon — July 4, 2024: Coincides with Independence Day and the UK election. The dark sky provides ideal conditions for observing the Crab Nebula (M1) on its anniversary.
- First Quarter Moon — July 13, 2024: Venus reappears in the evening sky, as recorded in the Dresden Codex on the Mayan day 1 Iq'.
- Full Moon — July 21, 2024: Known as the Buck Moon. On this date, asteroid 40 Harmonia reaches opposition at magnitude 9.4. Harmonia was discovered on March 31, 1856, by Hermann Goldschmidt.
- Last Quarter Moon — July 28, 2024: A good night for observing the Lunar Straight Wall (Rupes Recta), a fault scarp visible through telescopes.
Earth at Aphelion (July 5, 2024)
On July 5, 2024, Earth reaches aphelion — its farthest point from the Sun at 152.1 million kilometers (94.5 million miles). This event, calculated by NASA, occurs annually in early July. Despite being farthest from the Sun, summer in the Northern Hemisphere persists due to axial tilt.
Asteroid Oppositions: Ceres and Harmonia
Two significant asteroid oppositions occur in July 2024:
- Ceres at Opposition — July 6, 2024: The dwarf planet Ceres reaches magnitude 7.3 and is closest to Earth at 1.75 AU. This is the best time to view Ceres with binoculars or a small telescope.
- 40 Harmonia at Opposition — July 21, 2024: Asteroid Harmonia, discovered by Hermann Goldschmidt in 1856, reaches magnitude 9.4. It was named after the Greek goddess of harmony during post-Crimean War optimism.
Historical Significance: July’s Origins and Key Anniversaries
July’s name and historical weight are deeply rooted in Roman and astronomical history.
- Named for Julius Caesar: July was renamed in 44 BC to honor Julius Caesar, following his assassination. It was originally the fifth month in the Roman calendar (Quintilis) until the Julian reform extended it to 30 days.
- Gregorian Calendar Adoption: The Gregorian calendar, introduced by Pope Gregory XIII in 1582, established July as the 7th month with 31 days, aligning with Earth’s 365.2425-day orbit.
- Crab Supernova (SN 1054): Observed on July 4, 1054, by Chinese astronomers, this supernova created the Crab Nebula (M1). Its 970th anniversary in 2024 offers a unique opportunity for reflection on medieval astronomy.
- Asteroid Harmonia’s Discovery: Discovered in 1856, Harmonia’s naming reflected the hopeful post-war period after the Crimean War (1853–1856).

Astronomy Planning
- Best Viewing Nights: July 4 (New Moon) for deep-sky objects; July 6 for Ceres; July 21 for Harmonia and the Full Moon.
- Equipment Needed: Binoculars for Ceres (mag 7.3); a telescope for Harmonia (mag 9.4). The Lunar Straight Wall is best viewed on July 28.
- Aphelion Awareness: On July 5, the Sun appears slightly smaller in the sky (though not noticeable without special equipment).
Health and Environmental Observances
- Plastic Free July: Start preparing reusable bags, bottles, and containers in June. Many businesses offer discounts for reusable items.
