I am a Canadian citizen who entered Thailand July 15 last year on a tourist visa. I should have no problem entering Thailand July 1rst or 2nd this year on another tourist visa correct ? I believe I should be fine but I have seen some people talk about a year and a calendar year being different in some cases
TLDR : Answer Summary
A Canadian citizen who entered Thailand on a tourist visa and stayed for about 18 days should be able to re-enter Thailand on another tourist visa shortly after, without issues. Thai immigration rules allow for two visa-exempt entries by land within a calendar year and unlimited entries by air. The final decision for entry rests with the immigration officer. Based on past entry history, the individual in question is likely to face no problems when re-entering Thailand.
