The Bavli, M'gila, says that the seven servants that Ester had while in Hegay's harem were שהיתה מונה בהן ימי שבת, used by Ester to count the days of the week. Rashi explains שהיתה משרתת לה אחת באחד בשבת ואחת בשני בשבת ואחת בשלישי בשבת וכן כולן וכשהגיע יום שפחה של שבת יודעת שהיום שבת, that one would serve her on Sunday, another on Monday, another on Tuesday, and so on, so that, when the Saturday servant arrived, she [Ester] would know it's Shabas.
In Ester 4:16, Ester says she and her servants will fast three days. (She doesn't say all her servants will.)
- Did she still have a servant per day of the week? (Obviously I'm asking according to the midrash cited above.)
- If so, did all of them fast for three days, or did each fast only her day?
