The Hebrew Calendar is not measured in centuries, but Jewish tradition holds that the Exodus took place around the years 2400-2500. This is just a traditional number though, since no one truly knows when the events of the Hebrew Bible took place, if at all.
It is generally accepted by Christians that the journey to Egypt would have taken place about 1870 BCE. According to Genesis, Moses' grandfather, Kohath, was alive when the Israelites travelled to Egypt and lived 133 years, while Moses' father, Amran, lived 137 years. We do not know how old Kohath was when he went to Egypt, but if he and his son Amran were capable of fathering a child at any time between puberty and the year of their deaths, then Moses was born between about 1855-1600 BCE. On that evidence, Moses was born sometime during the 19th to 17th century BCE.
Another way of researching this is to work backwards from his death. The Book of Exodus says that Moses led the children of Israel out of Egypt at the age of about 80 years. The Book of Deuteronomy says that he died 40 years later at 120 years of age near the time when they were to enter the land of Canaan around 1400 BCE. Thus Moses would have been born around 1520 BCE, in the 16th century BCE.
