Application Dates for Essays on College Admissions Websites (UT Austin) - Please Clarify

The admissions website says “summer/fall 2020.” It also refers to “Spring 2020”. I graduate high school this year. Does this concern me or is this referring to the past or future pool of applicants? When I apply to colleges, will the dates say “summer/fall 2020”? It also says applying in August?? I thought you submit applications in January and December?? I am confused. I know I am applying to colleges this Fall/Winter (I’m a rising Senior) and expect to enter college next Fall as a Freshman. Thank you for your patience, I apologize for sounding a bit novice (the language is strange).

Applying in the spring semester in your senior year for colleges can put you at a disadvantage for schools that have priority deadline for admissions, scholarships or honors. Additionally, financial aid (UT recommends by January 15th).
