What should I consider about visa overstays in Thailand and how can I avoid mistakes when calculating my stay?

A user shared their experience of overstaying their Thai visa due to a misunderstanding of their visa stamp's date, resulting in a 1,000 baht fine. The discussion highlighted the importance of accurately calculating the 180-day stay limit and checking visa stamps carefully, as misinterpretations can lead to fines and being placed on immigration watch lists. Other commenters offered advice, suggesting to leave Thailand days before the visa expires and to maintain clear records of visa dates, noting common confusion arising from handwritten dates. The conversation also touched on questions regarding entry requirements, such as proof of funds.
