TOSFOS DH ELA D'KA'I B'CHAG V'KA'AMAR LAH B'NISAN
Check 1. Source #1, 2. Source #2 and (b) Clarification.
Why Tosfos says that lav davka in succos?, if source#2 says that Avraham Avinu was circumcised on Yom ha'Kipurim and source#1 says on the third day after his Milah the angels came to him. It is davka succos: kipur plus 3 days is actually succos

Yom Kippur is on the 10th of Tishrei and Sukos is on 15 Tishrei, so if the angels came to Avraham Avinu on the third day after the Milah that means they came on 13 Tishrei, which is why Tosfos says that Sukos is Lav Davka, because it was really two days before Sukos.
