This is the estimated original Japanese airing schedule for the first season of the Pokémon anime, that I have compiled, following the EP038 incident. This was really just for me to be able to make sense of the whole thing, and to be able to watch the episodes in chronological order.
This list is assuming one episode aired every week, except for two, and that every episode after aired in the right order, outside of EP052 and EP053.
This is assumed because every single episode that aired before this was aired every week, one a week.
Any two episodes between EP038 and The Purr-fect Hero, would likely have aired together on a single day. This is because there is no way the Todd arc would have been interrupted by the Kids Day episode.
The grayed episodes are the ones affected by the EP038 incident.
