We don’t currently have recurring tasks in Project.co. However this has been suggested on our feature requests page here: https://feedback.project.co/admin/board/feature-requests/p/recurring-tasks – If you upvote and comment on this feature request then we’ll keep you updated and notify you about it’s progress through our roadmap development stages.
At the moment dates on tasks can be fixed to 1 date or a date range.
Additionally, within templates dates can be set to be a set number of calendar or working days from the project start date. This is useful for scheduling tasks out from the start date based on standard timelines.
