Hi page, question re the TDAC if ok?

Reading the guides on embassy pages etc, states the TDAC must be submitted 3 days pre arrival ?

Is this 3 days the "no later than" or "no earlier than"?

Travelling to arrive 16th Aug, can submit now or way too early for the process ?

Thanks

Answer summary

The TDAC (Thai Declaration of Arrival Card) must be submitted no earlier than 3 days before your arrival in Thailand. It can be submitted as late as on the day of arrival, even at passport control.

It's "up to 3 days before arrival". You can even submit TDAC in the queue line for passport control at the entry point to Thailand.

You need to wait until the arrival date is selectable on the input calendar on the system. Wait for one month+.
