P.E.R.C.
Postal Employee Reference Calendar — map your NS days, Sundays, observed holidays, and annual leave for the year. Built for career regular carriers on a fixed bid schedule.

Set up your calendar

Enter one known NS day and (optionally) a planned leave block. Everything is calculated in your browser – nothing is sent anywhere.
One date you know is your non-scheduled day. The rotation is projected from here.
Many regulars have a fixed NS day; some bids rotate. Pick what matches your route.
First day of a leave block you want to visualize. Leave blank to skip.
Multiples of 8 (8 hrs = 1 work day). Off-days are skipped automatically.
Only turn this on if you have your real numbers from LiteBlue. It projects whether you’ll have earned the hours by your leave start date – it never invents a balance.
Your current banked / carryover hours. Enter your real figure.

What it does

The parts that matter.

🔄

Rotating or fixed, both handled

A non-scheduled day that steps forward each week is the whole reason this is hard to keep in your head. Tell it which day you are on now and which pattern you are on, and it works the rest of the year out from there.

🏖️

Annual leave laid over the top

Give it a start date and a number of hours and your booked leave lands on the same calendar as your NS days, so you can see the actual shape of the time off rather than two lists that need cross-referencing.

🧮

A leave balance check, if you want one

Enter your accrual rate and your current balance from LiteBlue and it works forward through the year, so you know whether the days you are eyeing are days you can actually afford.

📅

Accrual rates that match the service

Four hours a pay period under three years, six from three to fifteen, eight at fifteen and over. Pick the one that applies to you rather than working out the arithmetic yourself.

🔒

It never sees your details

The whole thing runs in your browser. Nothing you type is sent anywhere, stored, or attached to you — close the tab and it is gone.

Why this exists

A rotating non-scheduled day is simple to describe and miserable to plan around. It moves every week, so the day you are off in March is not the day you are off in April, and working out whether a wedding in July falls on a day you already have is a paper-and-pencil job every single time.

Every carrier I know has done that arithmetic in their head at a kitchen table. This does it once, for the year, in about four seconds.

About the balance check

The accrual figures built in are the standard ones — four, six or eight hours a pay period depending on years of service. It does the forward projection from the balance you type in.

That makes it a planning tool, not a record. It does not connect to LiteBlue and cannot know about leave you have already taken but not yet seen posted, or anything unusual in your own situation.

Check your real balance and your schedule in LiteBlue before you request anything. This tells you whether an idea is worth pursuing; LiteBlue tells you whether it is true.

What it does not do

It does not know your actual schedule — you tell it, it projects forward. It has no view of holidays, overtime, swaps, or anything your station does locally.

And it is not affiliated with the United States Postal Service in any way. It is a calculator I wrote because the arithmetic annoyed me.
