Today (April 16th, 2022) coincides with the popularly celebrated Hanumāna Jayantī (Hanumān's birthday) i.e, on Caitra Pūrņimā.
Although, from various sources, I have found at least 8 different dates assigned to Hanumān's birthday, out of them two are the most popular, as follows:-
1. the full moon of the month of Chaitra (March/April; Caitra pūrņimā)
2. the new moon of Karttik (Kārttik amāvasyā)
this book, this book, and several other, gives eight different birth-dates of Hanumāna
Date 1 is generally, the most popular, while Date 2 is observed by some people (for instance - the sadhus of the Hanumāna Garhi temple in Ayodhya, so I have heard)
In any case, the birth date (tithi) of Śrī Rāma has no ambiguity and is celebrated as Rāma navamī, the ninth of the bright fortnight (śukla-pakṣa) of the Chaitra month.
Question - Do the scriptures categorically mention who amongst Rāma & Hanumāna was born first?
Or can it be derived logically using scriptural evidence, who was [chronologically] elder amongst them?
