Importance of Calendar Versioning in API Development

Calendar versioning in APIs is crucial to signify changes in the API structure over time. It allows for differentiating between old and new versions, enabling smooth transitions and preventing disruptions in functionality. While extending APIs without changing the schema works initially, design decisions will evolve, leading to the need for updated endpoints and breaking changes. Constantly adding fields or duplicating old functionality can make the API structure messy after a few iterations, emphasizing the significance of calendar versioning.
