About FillDay: Canvas Date Auto-Filler
Are you a teacher who uses Canvas and spends way too much time manually setting due dates for every section?
FillDay fixes that.
Instead of setting the same due date over and over for each of your class sections, FillDay reads your bell schedule and fills in the correct date AND time for every section automatically — in one click.
How it works:
Set up your bell schedule once (takes about 2 minutes). Then on any Canvas assignment, open FillDay, pick your due date, and click Fill Dates. Every section gets the right time based on when that class meets. Done.
Works with:
Standard daily schedules
A/B alternating day schedules
Block schedules
MWF / TTh split schedules
Custom schedule types
Other features:
Automatically detects which period each section meets
Preserves extended time accommodations for students with IEPs/504s
Auto-saves the assignment when finished
Tiny floating badge — stays out of your way until you need it
Works on assignments and quizzes
Pricing:
7-day free trial, no credit card required. Then $1/month — less than a coffee.
Built by a teacher, for teachers.
