Creating a DCU Timeline For Batman and Superman

With a younger Superman appearing in Superman: Legacy in 2025 and a Batman movie featuring Damian Wayne on the way, questions about the timelines of these characters arise. How old is Superman? How long has he been around? How old are Batman and Nightwing and the rest of the Robins? When did Bruce become Batman? In this video I put together a reasonable timeline for how everything we know can fit together while maintaining a close enough gap range between Superman, Batman and the Batfamily!
