It's probably 20 years since I used MS Project in anger, but I'd have
thought it's overblown for that requirement, are you just looking for an
online calendar, or do you really want to be able to link dependencies
between tasks, determine how long tasks will take given different
numbers of volunteers etc?

You could probably get a 30 day trial of the online office365 version,
But after the trial, you'd need at least one "Professional" subscription
for £22/month and can have additional "Essentials" users at £5/month.

If Project isn't the thing, the cheaper office365 subscriptions give you
a calendar and a task planner ...
