I think that would be 2460 to 2960 in the Hebrew calendar.
He is Jewish after all.
You will often see BP (before present) too.
I have absolutely zero objection to Jewish researchers using the Hebrew calendar and wonder why a decision is made to infringe on the establishment of a Christian calendar.
The original Christian calendar, the one that preceded what we have today, was flawed as it did not account precisely for the imprecision of marking the time of Earth’s revolution around the Sun. This gave us leap years which is still off but not enough to make a difference over a very long time span.
The addition of leap years caused Christ’s birth to be moved from January 7 (old calendar) to December 25.
The Eastern Catholics, the Orthodox still have large sects among their followers that continue to observe the old calendar but even they adopted to include leap years to keep seasonal parity.
The Hebrew calendar is similarly flawed and that might be a reason Jewish historians avoid using it but I know from experience that some, not all and not even most, some Rabbis get ‘offended’ by the usage of BC/AD. I once told such a Rabbi that if he was going to change history so that he would not be offended, then he was condoning others to traverse a slippery slope. The offended become the offenders.
From a scholarly approach, the usage of calendars that are embedded in historical scriptures could be avoided entirely if associations of historians were convened to adopt a universal calendar that established a reference point such as say the date Caesar crossed the Rubicon or some such. People like me will continue to use the Christian calendar but will learn to cross reference a historical universal calendar to follow historical publications.
