High Key Planner

1 Paste your schedule from Aspen

In Aspen open My Info → Schedule and switch to the List view. Select the whole table, copy it, and paste it below. You can also type the rows by hand in step 2.

What the tool reads, and what it ignores

It only needs the Schedule column — text like 2(2,5) 3(3,6) means period 2 on rotation days 2 and 5, period 3 on days 3 and 6. That alone places every class. The Term column (FY, S1, S2) decides whether a course runs all year or swaps at the semester break. Course code, description and teacher are used for labels. Room numbers are not in Aspen's list view, so add them yourself in step 2 if you want them printed.

2 Check it, and add your rooms

Rooms are optional. Add a note to any class — a room, a supplies reminder, anything — and choose whether it prints every time, on one rotation day, or on one weekday.

Name on each page Weeks to print After-school block

Add a recurring note — before school or evening

Before school

Evening

A before-school note prints on its own row above the arrival time, so a late start is never hidden. Leave either row blank to skip it.

Right now

Today and tomorrow in full, and the week around them. This is the screen version — the printed pages cover the whole year.

3 Your schedule at a glance

Check this against your Aspen page before you print. Arrival and dismissal are worked out from the classes you actually have.

This tool was created for our BHS community by a family who needed it to figure out their kid’s wacky A2 blocks, but wanted to make it useable for everyone.

If you find this tool helpful, we would love you to consider a donation in any amount to the Innovation Fund at this special Planner Link. To maximize student privacy, no data is collected on this planner’s usage. Even a very small contribution will be a helpful signal that the tool is being used and valued so we know it’s worth improving and updating.

i Good to know

Day 6 dismisses early, at 2:15 PM — T2 block runs 1:55–2:15, then teacher collaboration.
Day 3 has no regular 5th period — T1 runs 1:55–2:25, then X Block until 3:05.
3rd period is split. Courses coded CE, FP, TE, MA, PA, SC, VA or WE take Class 1 first (10:54–12:04) then Lunch 2 (12:06–12:36). Courses coded EL, EN, ID, SO, SW, TU or WL take Lunch 1 first (10:49–11:19) then Class 2 (11:21–12:31).
If your first period is free, the planner gives you a later arrival time for that day.
Exam days, MCAS days and special-schedule days carry no rotation day, and no schedule for them is published — those pages are left blank to write in.
Check every row in step 2 before you print — the tool reads what you pasted, and a schedule that was copied short or stale will build a wrong year quietly.
Everything here runs on your own device. No account, no online service, and nothing you type is ever sent anywhere. One exception, so you know: the .xlsx download fetches the spreadsheet library from a public CDN when you click it, so that one button needs the internet. Your schedule is not part of that request.
Progress reports post in Aspen on Wed Oct 7, Tue Dec 15, Mon Mar 8 and Tue May 18. Quarters end Nov 9, Jan 28, Apr 12 and Jun 21.
Dismissal times for the Nov 25 and Apr 8 early-release days are not published. Check with the school.

Built from the BHS School Year Calendar 2026/27 and the district's per-block calendars. Always confirm against the school's own calendar before relying on it. This is not an official schedule.
