What Is the 1900s Century Called?

The years from 1900 to 1999 are commonly referred to as the 20th century. Although the decade‑starting year 1900 might suggest a “1900s” label, historians and calendar systems define a century by its first year ending in “01” and its last year ending in “00”. So naturally, the period that begins with 1901 and ends with 2000 constitutes the twentieth century, and the popular shorthand “the 1900s” is understood to mean the same era.

Naming Conventions: Why the 1900s Equals the 20th Century

The Gregorian Calendar Rule

The Gregorian calendar, which most of the world uses today, counts years sequentially from 1 AD onward. A century is defined as a block of 100 years that starts with a year ending in “01” and finishes with a year ending in “00”.

• 2nd century: 101 AD – 200 AD
• …
• 20th century: 1901 AD – 2000 AD

Thus, although the year 1900 belongs to the 19th century in this system, the colloquial phrase “the 1900s” is widely accepted as shorthand for the 20th century because the entire hundred‑year span is popularly associated with the leading digits “19‑” Most people skip this — try not to..

Common Usage vs. Academic Precision

In everyday conversation, media, and even many textbooks, you will hear references to “the 1900s” when discussing World Wars, the moon landing, or the rise of the internet. Academic works, however, often prefer the exact term 20th century to avoid ambiguity, especially when dealing with the transition year 1900 (which still belongs to the 19th century under the strict definition).
