Good question. The best I can come up with is the last week of Iyyar. [Keri'at Yam Suf of course was 21 Nissan, the seventh day of pesach, so a little more than a month later]. I say that because stop 7 was Alush, stop 8 was Rephidim, and stop 9 was Midbar Sinai, and they left Alush on 23 Iyyar and came to Midbar Sinai on Rosh Chodesh Sivan, so I'm figuring they were at Rephidim and attacked by Amaleik during the last week of Iyyar.
That does make sense. Thank you. If that's the case, you would surmise that Yisro came after matan torah?
