Editorial summary

How the Brownsville ISD ADSY/Extended Day calendar works

The ADSY schedule starts with two July blocks, returns for five Saturdays from January through April, and continues on selected weekdays in June. In all, the calendar marks 30 ADSY dates from July 20 through June 23.

Extended Day begins August 17 and is marked on 123 dates through May 13. The dates fall Monday through Thursday, with gaps around holidays, staff dates, early dismissal and other unmarked days.

Regular classes still run August 10-May 26, and participating students follow the district's major holiday breaks. November 11 and February 26 remain possible weather make-up days. The supplemental PDF does not list participating campuses or Extended Day hours, so families should confirm program eligibility and daily times with their school.

Common questions

Brownsville ISD 2026–2027 ADSY/Extended Day calendar FAQs

What is the Brownsville ISD ADSY/Extended Day calendar?

It is a supplemental schedule for students in participating ADSY or Extended Day programs; it does not replace Brownsville ISD's regular calendar. The PDF marks 30 ADSY dates and 123 Extended Day dates.

Who should follow the ADSY and Extended Day dates?

Only students assigned to participating ADSY or Extended Day programming should follow the extra dates. The PDF does not name the campuses, so families should confirm eligibility with their school.

Which Brownsville ISD campuses or grade levels participate in ADSY/Extended Day?

The district's ADSY/Extended Day PDF does not list participating campuses or grade levels. Families should confirm participation with their school.

What does ADSY stand for?

ADSY stands for Additional Days School Year, a Texas program that supports additional instructional days beyond the regular school calendar. Brownsville ISD's supplemental calendar marks 30 ADSY dates for participating students.

When is the first listed ADSY date?

The first ADSY date is Monday, July 20, 2026. The opening summer blocks run July 20-23 and July 27-30.

What is the last ADSY attendance date?

The final ADSY date is Wednesday, June 23, 2027, at the end of the June 21-23 block.

How many ADSY days are marked?

The calendar marks 30 ADSY dates: eight in July, five Saturdays from January through April, and seventeen weekdays in June.

Which Saturdays are ADSY days?

The five Saturday ADSY dates are January 30, February 6, February 20, March 6, and April 3.

What are the June ADSY ranges?

June ADSY instruction is marked for June 1-4, June 7-11, June 14-18, and June 21-23.

How many Extended Day dates are on the calendar?

The PDF labels 123 Extended Day dates between August 17, 2026, and May 13, 2027.

When does Extended Day programming begin and end?

The first Extended Day block begins August 17, 2026. The last marked block runs May 10-13, 2027.

Does Extended Day run every weekday?

No. All marked Extended Day dates fall Monday through Thursday, but Extended Day is not scheduled every Monday through Thursday. Holidays, breaks, staff dates, early release, and other gaps interrupt the schedule.

Are Extended Day start and dismissal times listed?

No. The PDF identifies the dates but does not print daily Extended Day hours. Families need to get program times from their campus.

When do regular classes begin for ADSY/Extended Day students?

The regular instructional calendar begins Monday, August 10, 2026. The July ADSY dates take place before that districtwide first class day.

When does the regular school year end on this calendar?

The regular last class day is Wednesday, May 26, 2027. ADSY programming then continues on selected dates through June 23.

Do ADSY/Extended Day students follow the district holiday breaks?

The supplemental grid retains Labor Day, Mini Fall Break, Thanksgiving Break, student Winter Break, Presidents Day, Spring Break, and Easter Break.

Is February 25 an Extended Day date?

No. February 25 is marked as the Charro Days early-dismissal date, not an Extended Day session.

Can November 11 or February 26 become attendance days?

Yes. Both are marked as student holidays and weather make-up options, so BISD may require attendance if lost instructional time must be recovered.

Do students attend every purple or green date?

Those colors identify Extended Day and ADSY dates, but attendance applies only to participating students. Campus instructions determine who is expected to attend.

Where is the official ADSY/Extended Day PDF?

The official download is linked on this page and is also published in Brownsville ISD's 2026-2027 School Year Calendars document collection.

About the Brownsville ISD 2026–2027 ADSY/Extended Day calendar

Data source

This page uses Brownsville ISD's 2026-2027 ADSY/Extended Day Calendar together with the board-approved regular instructional calendar. Every green ADSY date, purple Extended Day date, holiday, early dismissal, and weather make-up marker was checked visually.

How dates are handled

ADSY dates total 30 and Extended Day dates total 123. Consecutive marked dates are grouped, but weekends and unmarked gaps are never pulled into a range. Staff-only dates are excluded unless they change student attendance.

Updates

The supplied PDF does not list participating campuses or daily program hours. Those details should be added only from an official district or campus source.
