AnnuCal

AnnuCal is year planning software for people who think in months and quarters, not days and weeks. Standard calendars answer one question well: what happens next? They are built for the coming days. That makes them poor tools for the decisions that play out over a longer horizon, a product roadmap, a teaching year, a season of client work, the rhythm of a small business. AnnuCal answers a different question: what does the whole year look like? All twelve months sit on a single horizontal view. Where the year is dense and where it is empty becomes visible at a glance, without scrolling and without switching between month views. The product is built around a small set of ideas: Scenarios and calendars. A scenario is one plan, your year of client work, your family year, a project year. Each holds multiple calendars you can show and hide, so the same year can be read at different levels of detail. Time bars instead of dots. Anything that lasts longer than a day is drawn as a bar across the months it spans. Holidays, school breaks, projects and travel all read as duration rather than as single points. Public holidays and school breaks. Selectable by country and region, so the fixed structure of your year is there before you add anything of your own. Sharing. Plans can be shared as a read-only link, embedded on a website, or opened to named people as viewers or editors. Deliberately minimal. AnnuCal is not a project management suite. There are no tasks, no dependencies, no status workflows. It does one thing: it shows you a year, clearly. AnnuCal runs in the browser and is made in Hamburg, Germany.

Calendox

Calendox keeps Google Calendar, Microsoft Outlook and on-premises Exchange Server calendars in sync, shows them in one unified calendar, and offers booking pages that check every one of them. Sync one-way or multi-way between your connected calendars. Google and Microsoft changes land in seconds, recurring events included; Exchange Server changes arrive within about 5 minutes. See every calendar you have imported in a single view, and create, edit and move events from one place. Share booking pages whose availability is computed live across all of them, with a Zoom, Google Meet or Microsoft Teams link added when a booking is confirmed (Google Meet on a Google calendar, Teams on a Microsoft work or school calendar). Event titles, descriptions and locations are never stored in our database; they are read live from your calendar provider when displayed. Google and Microsoft calendars connect through OAuth, so Calendox never sees those passwords, and our Microsoft permissions exclude your email and files. On Personal and Business plans, an on-premises Exchange Server 2016 or later mailbox connects with its address and Exchange password, stored encrypted and sent only to that server. Signing in to Calendox itself needs no password. Business accounts add centralized subscription and seat management, member invitations and role-based access for teams. Enterprise is a separate account type: Microsoft 365 tenant-to-tenant sync between your organization and a partner, contractor, subsidiary or client tenant, connected through one admin consent per tenant and priced per imported calendar. Calendars are paired automatically when both the email username and the calendar name match. Enterprise is sync only, with no booking pages or unified calendar. 14-day free trial, no credit card required, at calendox.com. Also available on Microsoft Marketplace, billed through your Microsoft account.
