USPS Calendar
Work out which day you are actually off, for the whole year, from one rotating schedule — and check whether your leave balance covers the days you want to book.
Nothing to install — it runs in this page.
Set up your calendar
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.
From download to done.
Pick the non-scheduled day you are on this week.
Choose whether your NS day rotates or stays on the same weekday.
Add annual leave dates and hours if you are planning around them.
Tick the balance check and enter your accrual rate and LiteBlue balance if you want the running total.

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.
