375-350 BC, as stated by Dubois
issued in the seventh year of the kingdom of Ptolemy (i.e. Ptolemy III) son of Ptolemy (II) and Arsinoe (240 BC), on the second day of the month Dystros (February: Dittenberger et alii; May-June: Sherk), under the priesthood of Theodotos
320-310 BC (see the commentary)
around or before 500 BC
426/5 BC
The lines 1-70 of CID II 31 record the transactions from the autumn-pylaia of Argilios (358/7 BC) until the spring-pylaia of Theucharis (352/1 BC). The accounts of CID II 31 and CID II 32 were clearly planned and cut as a single job in or just after Maimalos’ year, 311/10 BC, or later (CID II 32, l. 100)
Both palaeography and orthography seem to be consistent with a 1st century BC dating, probably around 50 BC
