According to Roman writer Censorinus, the Egyptian New Year's Day fell on July 20 in the Julian Calendar in 139 AD, which was a heliacal rising of Sirius in Egypt. From this it is possible to calculate that the previous occasion on which this occurred was 1322 BC, and the one before that was 2782 BC. This latter date has been postulated as the time when the calendar was invented, but Djer's reign preceded that date. Other historians push it back another whole cycle, to 4242 BC.
