All these dates as calculated by Zuckermann are separated by an integral multiple of seven years, except for the date associated with the siege of Beth-zur. Furthermore, his chronology is consistent with that accepted by the "geonim" (medieval Jewish scholars) and the calendar of Sabbatical years used in present-day Israel. All of this would seem to be strong evidence in favor of Zuckermann's scheme. Nevertheless, some problems have been recognized, beyond just the question of the siege of Beth-zur, which was one year too late for Zuckermann's calendar. A consistent problem has been the ambiguity alleged in some of the passages, notably of Josephus, where it has been questioned, for example, when Josephus started the regnal years of Herod the Great. In a study the chronology of all Herod's reign, Andrew Steinmann presents arguments in favor of dating Herod's capture of Jerusalem in 10 Tishre of 37 BCE, i.e. just after the Sabbatical year of 38/37, based on references to the activities of Mark Antony and Sosius, Herod's helpers, in Cassius Dio (49.23.1–2) and also on other considerations. This date is in agreement with Ben Zion Wacholder's chronology. Therefore, many modern scholars have adopted a Sabbatical year calendar for the Second Temple period that is one year later, although there are many prominent scholars who still maintain a cycle consistent with Zuckermann's conclusion of a 38/37 BCE Sabbatical year.
