Welcome. Every guide below is short, practical, and written for people who juggle more than one calendar: contractors, consultants, and fractional executives with a client login for everything. One thing worth knowing before you dive in: manyCalendars runs 100% locally in your browser. No cloud sync, no account needed for the free tier, no admin rights, and your calendars are read and merged on your device, not in our cloud. The guides tagged Pro cover features included with a paid plan. You can compare plans on the pricing page.

Getting started

Getting started: your first merged calendar view

Install the extension and merge your first calendars into one private view. Free for unlimited calendars, no account needed.

Copy your availability in one click

Turn your free time across every calendar into clean text you can paste into any email or chat.

Calendars

Add a calendar with a secret ICS address

Pull in any calendar that offers a private ICS feed, including Google Calendar and Outlook.

Read the guide Pro

Sync a calendar from a browser tab

Bring in calendars IT will not let you export. If you can see it in a tab, you can capture it.

Customization

Change calendar and event colors

Give each calendar its own color so you can tell clients apart at a glance.

Switch themes

Change the look of your merged view in a couple of clicks.

Read the guide Pro

Privacy Mode appearance and skins

Turn your merged view into a neutral, generic calendar so another client's details stay off a shared screen.

How-to guides

See all your calendars in one place

Three honest ways to get every calendar into one view: one provider, ICS feeds, or a browser extension that merges them.

Merge Google and Outlook calendars

Two ways to merge them: ICS feeds when export is allowed, Tab Sync when IT blocks it. Numbered steps for both.

Combine work and personal calendars privately

One private view of both, without giving your employer visibility into your personal life.

Avoid double booking with multiple clients

Use one merged view and conflict detection so a missed overlap never costs you a client.

Check multiple Outlook calendars at once

Stop cycling through Outlook tabs. See every Outlook account in one merged grid, no admin approval.

See your work calendar without IT help

No ticket, no waiting, no asking. Read your calendar straight from the tab you are already signed into.

Share availability across multiple calendars

Compute free slots from every client calendar and copy a clean summary, no back-and-forth.

Hide calendar details when screen sharing

One keystroke swaps your multi-client view for a neutral, generic calendar while you present.

Get meeting reminders from every calendar

One reminder stream across all your calendars, so a meeting on a forgotten calendar never blindsides you.

Track time zones across client calendars

Pin live clocks for every client city next to your merged calendar instead of converting in your head.
