Namaskaram, I have been waking up everyday at 4:50 am and trying to finish my prayers (Perumal Suprabatham, Vishnu sahasranamam and Thiruppavai) before 7:00 am. This is my understanding that the rakashasa kalam starts at 7:00 am and it is ideal to not pray after that. I have been looking and searching in this forum to confirm my understanding regarding the best time to pray during the day. I would immensely appreciate any input/advice on this matter. Sincerely, Satish
