Above snippet would result in Unable to find a dawn time on the date specified
The reason is because the initial calculation would give the tot (time of transit) as 2024-05-18 05:29:42.178336+05:30, and then its date (2024-05-18) is used to compare against (2024-05-17), which would adjust the input date to 2024-05-16, thus the ValueError.
Proposed solution: the initial date comparison between tot and input date should account for timezone.
