Okay, I'm going to register for the ACT, on their website it says

Registration Deadline: February 27, 2009

Does that mean starting tomorrow, I'll be late? Or tommorrow will be the last day to register?

Tomorrow is the last day to register. After that, it'll be late.

ahh okay. Thanks.

Based on the information you provided, it seems that the registration deadline for the ACT is February 27, 2009. This means that you would need to register by that date in order to meet the deadline.

To clarify, if tomorrow is February 27, 2009, then it would be the last day to register. If it is any day after that, registering would be considered late and may not be accepted. Keep in mind that this answer assumes that the information you provided accurately reflects the current registration details for the ACT. It's always a good idea to double-check with official sources like the ACT website for the most up-to-date information.
