How many years does it take for a dinosaur egg to hatch?

I'm curious, how long does it actually take for a dinosaur egg to hatch? Is the process similar to that of modern birds, where the incubation period can vary based on the species? Or is there a general timeframe that applies across all dinosaurs? Additionally, are there any factors that could influence the hatching time, such as temperature or humidity? I'd love to learn more about this fascinating aspect of dinosaur biology.
