7月1日英文名來源｜Why July Is Called July
每年的7月1日，不少人都會翻開新的月份，但你是否想過，為什麼七月的英文叫做 July？這個名字背後，其實與古羅馬歷史、一位改變世界的人物，以及曆法改革有著深厚關係。
July marks the beginning of the second half of the year, yet few people stop to wonder where its English name originated. Behind the word “July” lies a fascinating story involving ancient Rome, a legendary leader, and one of history’s most influential calendar reforms.
中文
七月（July）的名字源自古羅馬最具影響力的人物之一──凱撒大帝尤利烏斯．凱撒（Julius Caesar）。然而，七月最初並不叫 July，而是名為 Quintilis，意思是「第五個月」。這是因為早期的羅馬曆法只有十個月份，一年從三月開始，因此 Quintilis 排在第五位。後來，羅馬王努馬．龐皮留斯（Numa Pompilius）增設了一月與二月，曆法改為十二個月，Quintilis 雖然變成了第七個月，但名稱一直沿用。公元前44年，凱撒遇刺身亡後，為了紀念這位改革羅馬共和國的重要人物，羅馬元老院決定將 Quintilis 改名為 Julius，以表彰他在政治、軍事及曆法改革上的巨大貢獻。隨著拉丁語逐漸演變成現代歐洲語言，Julius 最終演變成今天英文的 July。凱撒最重要的成就之一，是推行著名的「儒略曆」（Julian Calendar）。在此之前，羅馬曆法因政治因素經常被任意調整，導致季節與月份逐漸錯亂。凱撒邀請埃及天文學家協助改革，以太陽年約365.25天作為基礎，制定一年365天，每四年增加一天閏年的制度，大幅提升曆法準確度。這套制度影響了歐洲超過一千六百年，後來雖然被更精確的格里曆（Gregorian Calendar）取代，但今日世界仍沿用其基本架構。值得一提的是，七月也是北半球盛夏開始的重要月份，象徵陽光、收穫、旅遊與假期；在南半球則正值冬季，展現地球四季相反的自然現象。世界各地亦有不少重要節日和歷史事件發生於七月，例如加拿大國慶、日本多項夏祭，以及不同國家的獨立紀念日，都令七月成為充滿活力與文化色彩的一個月份。當我們今天寫下 July 這個簡單的英文單字，其實同時承載著二千多年前古羅馬文明的記憶，也提醒人們，一個名字不只是語言符號，更是一段歷史、一位人物，以及一場改變世界的制度改革所留下的印記。每當七月來臨，我們迎接的不只是新的一個月份，也是歷史與現代生活跨越千年的連結。
English Version
The English name July carries far more history than most people realize. Long before it became the seventh month of the modern calendar, it was known in ancient Rome as Quintilis, meaning “the fifth month.” This seemingly strange name makes sense because the earliest Roman calendar began in March and contained only ten months. When January and February were later added, Quintilis moved into the seventh position, although its original name remained unchanged. Everything changed after the death of Julius Caesar in 44 BC. Recognized as one of Rome’s greatest military commanders, political leaders, and reformers, Caesar had reshaped not only the Roman Republic but also the way people measured time. To honor his extraordinary legacy, the Roman Senate officially renamed Quintilis after him, creating the Latin name Julius, which eventually evolved into the English word July through centuries of linguistic change. Caesar’s influence extended well beyond politics. Before his reforms, the Roman calendar had become unreliable because officials frequently adjusted it for political purposes, causing the seasons and calendar dates to drift apart. Seeking a lasting solution, Caesar introduced a new solar-based calendar with the assistance of Egyptian astronomers. The Julian Calendar established a year of 365 days with an extra leap day every four years, creating a far more accurate system than its predecessor. This innovation became the foundation of timekeeping across Europe for more than sixteen centuries. Although the Gregorian Calendar later refined the calculation slightly to improve long-term accuracy, its structure remains deeply rooted in Caesar’s original design. Today, July represents very different experiences depending on where people live. In the Northern Hemisphere it brings sunshine, school holidays, festivals, travel, and the heart of summer, while in the Southern Hemisphere it marks the middle of winter. Around the world, many nations celebrate important historical anniversaries, national holidays, and cultural festivals during July, giving the month a unique global significance. Every time we write or speak the word “July,” we unknowingly preserve a connection to one of history’s most influential civilizations. What appears to be an ordinary month on a calendar is actually a lasting tribute to a remarkable leader whose reforms transformed the measurement of time itself. More than two thousand years later, the name continues to remind us that history lives quietly within the words we use every single day.
