The four inputs

Services. The weekly pattern (a Saturday Vigil and two Sunday Masses, or an early service, a parish Eucharist and Evensong) plus one-off feasts such as Christmas Eve. Ministries. The roles, with how many of each are needed at each service. People. Names or initials, what each person is trained for, the services they prefer, the dates they are away, how often they are willing to serve, and who serves as a family or a pair. Rules. The parish's own: PewRota ships none of its own beyond the three that every rota keeps (trained, available, one role at a time).

A quarter, worked

The sample parish in the rota builder has 56 people and three Masses a weekend. From December to February that is 13 weekends, 39 Masses and 442 places, 34 each weekend. Built with every rule on, 442 of the 442 places are filled with no rule broken, and turns range from 6 to 9 per person over the quarter. A spreadsheet can hold that grid; keeping 442 places consistent with every person's dates, limits and family by hand is where it goes wrong.

Every guide

How long it takes

The first quarter takes an evening: type or paste the list, tick who does what, and add the dates people have already said they are away. After that, each new quarter is a matter of minutes. Close the old quarter on the Drafts and quarters tab so its turns carry forward, add any new volunteers, remove anyone who has stepped down, and build again. Keep the places that are already agreed by locking them before you rebuild; the builder works around them.

When someone cannot make a date, change the rota by hand in the review grid. Drag the name to another place or pick someone for the open place from a list that says who is free and why the others are not. A hand change that breaks a rule is allowed, because the scheduler may know something the tool does not, but it is flagged until it is fixed.

What makes a rota trusted

Volunteers stop swapping in private when they can see the rota is fair. Three things help: the same rules for everyone, written down; a fairness report that shows who served how often; and an honest list of the places that could not be filled, with the reason, so the scheduler can ask for help instead of stretching the same five people. PewRota prints all three.

Frequently asked questions

Where should a new scheduler start?

With the list of services and how many of each ministry each one needs. Then the people, then the rules. The fair rotation guide explains each rule.

How long does a quarter take to build?

Entering a parish for the first time takes as long as typing or pasting the list. The build itself takes well under a second for a quarter on an ordinary computer.

Can I keep using my spreadsheet?

Yes. Paste from it to add people, and export the finished rota as a CSV back into it, or print it.
