The old name of Kolkata was Calcutta. The city was officially known as Calcutta during British rule and for several decades after India's independence. In 2001, the Government of West Bengal officially changed the English name from Calcutta to Kolkata to better reflect the city's original Bengali pronunciation, "Kôlkata" (কলকাতা) and its local linguistic and cultural identity. The change was formalized under the West Bengal Capital City (Change of Name) Act, 2001.
Although the official name changed, the city's rich history, literary heritage, architecture, cuisine, and traditions remain deeply rooted in its past. Today, Kolkata continues to be known as India's "City of Joy" and one of the country's most important cultural, educational, and intellectual centers.
| Name | Time Period | Meaning / Background |
|---|---|---|
| Calcutta | Official English name until 2001 | Anglicized version introduced during British rule. |
| Kolkata | Official name since 2001 | Reflects the original Bengali pronunciation "Kôlkata." |
| Kolikata (Kôlikata) | Historical local name | One of the three villages from which modern Kolkata developed. |
The city's present name is not entirely new; it is a return to its historical local pronunciation rather than the creation of a completely different name.

Reason for the Change
The name was changed for several reasons.
-
To reflect the city's original Bengali pronunciation.
-
To strengthen the city's cultural and linguistic identity.
-
To reduce the influence of the colonial English spelling introduced during British rule.
-
To align the official English name with the name long used by local residents.
This was part of a broader trend in India where several cities adopted names closer to their native languages and historical identities.
