Teach your workflows the days you don’t work
A Business Calendar is a shared list of your holidays. Attach one to a workflow and every date it computes starts skipping the days your team is off — weekends and the holidays you define. Due dates count in business days, and a date that still lands on a day off snaps to a real working day or, for a recurring run, moves or skips.

Stop scheduling work on days nobody’s in
A recurring workflow doesn’t know it’s a holiday. Left alone, a “due in 3 days” step lands on the 4th of July, a reminder fires while the office is closed, and a monthly run kicks off on New Year’s Day. A Business Calendar teaches your workflows the days your team actually works.
- Due dates land on public holidays
- Reminders fire while the office is closed
- Recurring runs start on a day off
- Holidays skipped alongside weekends
- Dates snap to a real working day
- Recurring runs move or skip the holiday
One calendar, three ways it shows up
The calendar itself
A shared, account-wide list of the dates your team is off — imported from a regional template and topped up with your own custom closures.
Due dates & reminders
Business-day counting steps over the calendar’s holidays, and a landing rule snaps a computed date off any day off it still hits.
Recurring runs
A scheduled run that falls on a holiday or weekend can move to the next or previous business day — or skip that occurrence entirely.
Set it up once, in three steps
Build a calendar
Under Settings → Holiday Calendars, add a calendar and import a regional template — US, UK, Canadian, or Australian dates. Add any custom closures the template can’t know about.
Attach it to a workflow
Point a workflow at the calendar. From then on its holidays count as non-business days everywhere that workflow works with dates.
Choose how dates behave
Set the workflow’s landing rule for due dates and reminders, and the weekend/holiday rule for its recurring schedule. Each run stamps these when it starts.
Import your region, then make it yours
Import a regional template and Manifestly fills the calendar with the observed holiday dates — shifted to the weekday offices actually close on, not the raw date on the wall calendar. Those imported dates sit alongside any custom dates you add, each clearly marked, and the whole calendar is yours to edit.
- Templates for the US, the UK (England & Wales), Canada (Ontario), and Australia (NSW).
- Add custom dates — a founders’ day, a company-wide shutdown week, a floating closure.
- Imported calendars extend themselves ~5 years ahead automatically, so you never re-import each January.
Due dates that count business days — and land on one
Business-day counting already steps over weekends and the calendar’s holidays, so “due in 3 business days” reaches a day people are working. The landing rule handles the edges — a due date anchored to a fixed day, or a reminder that happens to fall on a holiday. Pick the behavior once and every run of that workflow follows it.
Recurring runs that don’t start on a day off
A schedule that fires “on the 1st” or “every Monday” will eventually land on a holiday. With a calendar attached, the schedule treats those holidays like weekends — and you choose what happens when an occurrence falls on one.
Skipping is unique to recurring runs — a due date is always moved to a real day, but a scheduled run can simply sit out a holiday.
Predictable, and under control
- Calendars are account-wide, so one set of holidays serves every team that attaches it.
- Only master admins create and edit calendars — the days-off rules stay centrally managed.
- Each run stamps its workflow’s calendar and rules when it starts, so a change never reshuffles the dates of runs already in flight.
- Past the calendar’s last covered date, dates simply fall back to weekends-only — a coverage badge shows how far ahead you’re set.
Manage it by hand or over the API
Everything you can do in Manifestly you can also drive through the v2 API — import a region onto a calendar, add a custom date, attach a calendar to a workflow, or set its landing rule from your own tooling.
- Create calendars, generate regional dates, and add individual holidays.
- Attach a calendar and set the business-day rule per workflow.
- AI agents can manage calendars over MCP — ask in plain language and let the agent generate the dates.

A template is a starting point — once imported, the dates are yours to add to or trim.
Where a Business Calendar earns its keep
Finance & accounting
Month-end and payroll close on the right working day.
“Close by the 3rd business day” counts past the holiday instead of landing on it.
Compliance & filings
Deadlines and review reminders stay on business days.
A filing reminder that would fire on a bank holiday snaps to the previous business day.
Recurring operations
Daily and weekly runs step around holiday closures.
A daily open-store run skips the holiday, then resumes the next business day.
