International Translation Day is observed every year on 30 September, celebrating translators, interpreters, and language professionals who help the world communicate across linguistic boundaries. The date commemorates the feast day of St. Jerome, the patron saint of translators, who produced one of the earliest major translations of the Bible. Since 2017, this observance has been recognised globally by the United Nations, acknowledging that translation is essential for peace, cooperation, and global understanding.
Why Translation Matters More Than Ever
In an increasingly connected world, translation is not simply about converting words from one language to another; it is a cultural bridge that preserves meaning, context, identity, and heritage. More than 7,100 languages are spoken worldwide, yet around 40% are endangered and risk disappearing without preservation efforts. For millions of people who do not read or speak English, translation is a lifeline that enables access to education, technology, literature, healthcare, and justice.
A Powerful Global Industry
The translation and language services sector is one of the fastest-growing knowledge industries, driven by digital communication, global trade, and migration.
- The global translation and interpretation industry was valued at around $60 billion in 2024.
- It is projected to exceed $72 billion by 2028.
- More than 640,000 professional translators and interpreters work worldwide.
- Despite advances in AI, human translators remain essential for tone, cultural nuance, and emotional depth.
Empowering Voices Beyond English
Although English is widely used in global communication, only about 18% of the world’s population speaks it, and fewer than 6% speak it as a first language. This means more than five billion people depend on translation to access global knowledge. Translation turns exclusion into participation by helping migrants rebuild lives, enabling students from small language communities to compete internationally, and ensuring access to critical information during crises such as health emergencies, conflicts, and natural disasters.
Protecting Culture and Identity
Languages carry memory, history, and worldview, and when languages disappear, cultures weaken. Translation protects cultural diversity by making literature, folklore, scientific research, legal documents, and historical texts accessible across borders. Major literary traditions—from Bengali poetry to Latin American novels and European classics—reached global audiences through translation. Yet UNESCO estimates that only about 10% of world literature is translated, leaving countless voices unheard and making translation a matter of cultural justice.
Challenges Faced by Translators
Despite their importance, translators often work behind the scenes and face challenges such as limited recognition, low wages, tight deadlines, emotional stress in humanitarian or conflict settings, and the misconception that artificial intelligence can fully replace human expertise. Many professionals argue that AI should support, not replace, human translators, and that quality training, fair compensation, and ethical standards are essential for the future of the profession.
A Call to Celebrate and Support Translators
International Translation Day reminds us that without translators, the world would be fragmented and isolated. Every translated book, film subtitle, medical instruction, or peace negotiation reflects the work of someone committed to understanding rather than division. By celebrating this day, we honour the invisible bridge-builders who keep the world connected, informed, and culturally enriched, proving that translation is not just about words but about making the world accessible to everyone.
