Re: Eid-e-Milad-ul-Nabi … and reason we Muslims celebrate the day.
Brother, I got your point.
… anyhow, I think there is flaw in what you understood.
If ayah of Quran is saying that Prophets (AS) are blessed and not those particular days in the life of that Prophets (AS) are blessed, then there was no need to specifically mention 3 particular days and that also associating these 3 particular days twice (in case of 2 Prophets), as Prophets (AS) life is always blessed … as Prophets are not even going through test, rather they are representing Allah and have support of Allah throughout … but days can be special for a person or not, be that person Prophet (AS) or ordinary person. Hence the message in Quran by Allah would have been that:
For Yahya (AS) in words of Allah: He (AS) is blessed
And for Isa (AS) in words of Isa (AS): I am blessed
