Effectively storing, transmitting, and restoring instances of datetime objects remains critical in modern software development, particularly concerning APIs, databases, logging, and caching mechanisms. Unfortunately, native datetime objects fail to serialize directly into widely adopted formats like JSON or XML.

Therefore, learning efficient serialization techniques becomes indispensable for smooth integration with diverse technologies.

This tutorial explores three prominent Python serialization approaches compatible with datetime objects: JSON, Pickle, and XML. Furthermore, discover deserialization procedures necessary to restore serialized content back into functional datetime instances.

JSON Serialization

Although JSON natively supports numeric, boolean, null, array, and dictionary data structures, it lacks built-in support for datetime objects. Bridging this gap necessitates defining helper functions mapping datetime values to JSON-compatible counterparts before encoding them into strings.
