When 27 August, fifteen days before 7 September, passed without a reply from either Sadat or Assad, it was clear no offensive would take place in September. During 28 and 29 August, Sadat met with Assad in Damascus, where they agreed to start the war in October. They specified October 6 as D-Day, and informed Ahmed Ismail and Tlass on 22 September, who in turn relayed the decision to the Chiefs of Staff. At the request of Ahmed Ismail, Sadat produced a presidential directive for war. Therefore, it was only in September, less than a month before the attack, that the date October 6 was finally selected as D-Day. The coordinated offensive would begin at 14:00 (Cairo Local Time). October 6 was chosen for several reasons. The speed of the water current and the tide were optimal for a crossing operation, and for most of the night there was a full moon, facilitating bridge construction. The date coincided with Yom Kippur, the Jewish Day of Atonement. This was an important factor in choosing October 6 for an attack; observant Jews fast on that day, abstain from the use of fire or electricity (which meant transportation would be at a standstill), and much of the Israeli army would be demobilised. October also coincided with the month of Ramadan in the Muslim Calendar, which meant that Muslim soldiers would be fasting. It was in Ramadan that the Muslims won their first victory at the Battle of Badr in the year 624. Opting for something more inspirational than the High Minarets as a name, Operation Badr was chosen by Egyptian commanders as the codename for the assault.
