Jan 1st deadline

I assume it is 11:59PM on Jan 1st, am I right? Thanks!

No reason to assume on something this important.

From https://appsupport.commonapp.org/link/portal/33011/33013/Article/35/When-is-the-deadline-for-my-application-submission

"
To meet an application deadline, you must submit your application materials by 11:59 pm on the deadline date posted on your Dashboard. The end of the deadline date is in your local time zone, not the college’s time zone. Keep in mind, all timestamps are recorded in EST (US Eastern Standard Time).
It is always better to submit well before 11:59 pm to avoid last minute issues with your computer or internet access that might cause you to miss the deadline!"
