Understanding TDAC Timing: 72 Hours vs 48 Hours and Re-Entry Rules

TDAC instructions mention 72 hours and 48 hours but you cannot figure out what each one means. Do you submit your digital arrival card 72 hours before arrival or 48 hours. If you mess up the timing, will immigration reject your entry at the airport. The rules seem deliberately vague and your flight arrives in three days, so you need clarity immediately.

TDAC timing requirements are confusing because the official language mixes maximum submission windows with recommended submission windows. Nobody explains what actually happens if you submit outside these windows or how to handle multiple entries if you leave and return to Thailand.
