Hare Krsna Dear Gurudev,
Please accept my humble obeisances at your lotus feet.
All glories to Srila Prabhupada.
All glories to Guru parampara.

1. Do we have any specific scripture / book for to know about Krsna's daily schedules?

HpS - "Lord Krsna's Daily Activities" in the KRSNA book, no?

2. Do we have any specific scripture / book for to know about demi god's residential information in different planets?

HpS - As I remember the story of when Bali Maharaja conquers Indra in the SB may describe Amaravati. Proabably 9th Canto. Then the Fifth Canto may have some eg. the chapter "Subterrenean Heavenly Planets".

Thank you so much Gurudev.

your fallen servant,
Girivaradhari-Gopal Das

HpS - Thank you.  Let's go to the next letter.
