TLDR : Answer Summary
Users are experiencing issues setting their arrival date in the online application system for Thailand, specifically for a date of May 2nd. The primary reason for the error is that the application only accepts dates submitted within 3 days prior to the arrival date. Several comments clarify that applications can be submitted starting from May 1st for a May 2nd arrival. The conversation reveals confusion among users regarding this 3-day rule and emphasizes the importance of adhering strictly to this timeline to avoid frustration.

Counting back 3 days seems to be difficult for a lot of people.

it's nothing complicated. A few lines to fill in like the boarding card of before that you filled in on the flight over. Simple.

You can even fill it in on arrival standing in the queue if you have WiFi.

Stop panicking folks please! It is only the same details required as on the paper form,now digital! And the Thai authorities have said they'll assist people at the airport literally just before going through immigration if necessary! They want to try and make it easier for genuine tourists/ visitors! They need and want your dosh!

Plus I've noticed that several folks have commented that they'll visit neighbouring countries, if Thailand's bureaucracy makes entry too complicated! The Thais will not want that!

thats what is freaking people out as there hasn't been a paper form for 3-4 years now and none of the questions you need to answer online are asked at immigration now so I'm not sure about it making things quicker as there will still be crazy long queue's

@Dennis *********
why would you freak out over filling in a form. People book flights on line, buy stuff on line, but become freaked out over putting travel info on an online form.

@Lynnette ******
don't ask me ask the people who make posts every day about it , doesn't matter how many times it's explained to do it within 3 days of arrival they still post asking about every day , not just on FB but on all the socials, maybe there new to Thailand and haven't had to fill out a tm6 before

Come on mate.. Clearly says within 3 days, 72 hours before.
Lynnette *******
The "3 days" seems to confuse people. 3 is 3. It's not 4 it's not 6 or 10. It's 3. Just count backwards from day of arrival. Apply on any of those 3 days.

@Lynnette ******
that's a lot of posts from companies, influencers, embassies, airlines that was not able to read within 3 days correctly and used minimum 3 days before in dozens of posts, articles and videos....

Lynnette *******
@Sharon ********
can you not count back 3 days from date you arrive? And apply on any of those dates.

@Sharon ********
you can apply on the 3rd, 4th or 5th.
THAI ******************************
You need to wait until Tomorrow.

The system only allows 3 days before arrival date.
