Estimating the number of hours since the world started depends on the definition of "world." If we consider the age of the Earth to be about 4.5 billion years, that translates to roughly 39.5 billion hours. This calculation is based on multiplying 4.5 billion years by the average number of hours in a year (approximately 8,760). However, this is a simplification and actual estimates can vary based on geological and astronomical factors.
