How does one determine age eligibility for Juvenile

[Abbyar]

I’m trying to determine if Dd will be young enough for Juvenile next year.

She will turn 12 in August 2019. Is the requirement for the 2019-2020 season to be under 13 by September 1, 2019, or 2020 as it will be the 2020 season?

Thanks-

Since the OP's DD skated at UDel, we can assume she's a US skater. 

The age cutoff is in the Rulebook, which is valid through June 30th, 2019.  http://www.usfsa.org/content/2018-19%20Rulebook.pdf

On page 193, it says:

6450  Juvenile Singles and Open Juvenile Singles
Note:  Open juvenile singles events are considered nonqualifying events and are held at a regional championship only at the discretion of the local organizing committee.

A. Test qualifications as of the closing date for entry to the regional championships: Juvenile moves in the field test or higher, and juvenile free skate test but no higher.

B.   Age requirements as of Sept. 1 prior to the regional championships:
 1.   Juvenile: 12 years of age or younger for girls; 13 years of age or younger for boys
 2.   Open Juvenile: 13 years of age or older for girls; 14 years of age or older for boys

Age cutoff change proposals can be found on Members Only before the meeting.
After the GC meeting, the passed proposals are logged on the GC webpage here: http://www.usfsa.org/story?id=84154&menu=leadership

IF a change in the age cutoff is proposed and passed at the Governing Council (GC) meeting in Spring 2019, it will be published over the summer in the official Rulebook.
