What is the maximum duration for staying in Thailand within a calendar year?

In Thailand, there isn't a strict rule on how many days you can stay, but immigration officers generally become cautious if you exceed 90 days within a 6-month period or stay for 6 months in a calendar year. Many travelers report successful stays of up to 6 weeks at a time without problems, provided they don't draw attention with frequent back-to-back visits. It's suggested to be mindful, as ultimately the immigration officer has the final say on your entry. One commenter humorously noted a 365-day maximum, while others discussed their personal experiences with visa exemptions.
