CalendarTree was a scheduling service.


I recently had the opportunity to try out CalendarTree, a scheduling service designed to simplify the process of booking appointments and managing schedules. As someone who frequently juggles multiple commitments and appointments, I was excited to see if this service could help streamline my busy schedule.

Upon signing up for CalendarTree, I was impressed by the user-friendly interface and intuitive design. The service allows users to easily create and customize their own booking pages, which can be shared with clients, colleagues, or anyone else who needs to schedule time with you. With features like automatic time zone conversion and integration with popular calendar apps like Google Calendar and Outlook, I found that CalendarTree made it easy to keep track of all my appointments in one place. I am sad it is no longer available. I did some research and found these options:




These tools can be a great help whether you’re coordinating a work project or planning a family reunion.

  1. Google Calendar: Google Calendar is like your personal assistant. It helps you keep track of your appointments, meetings, and reminders all in one place. Not only can you create events and share them with others, but Google Calendar also updates any changes in real-time. You can color-code events for easy organization, and best of all, it’s free and integrates seamlessly with other Google services.
  2. Microsoft Outlook Calendar: If you’re more into the Microsoft ecosystem, their Outlook Calendar might be your best friend. Part of the Microsoft Office suite, it offers extensive scheduling capabilities, including sending meeting invitations via email and tracking attendees’ responses. It’s a workhorse for office settings, but also adaptable for personal use.
  3. Calendly: Ever had trouble finding a common free slot for a meeting? Calendly solves that problem. This smart tool lets you define your available times, then others can pick a slot that works best for them. It integrates beautifully with Google Calendar, Outlook, and iCal, ensuring no double-booking happens.
  4. Doodle: Planning a group event? Doodle to the rescue! You propose potential times for an event and participants vote on their availability. This democratic approach makes scheduling group events a breeze. Plus, Doodle integrates with your existing calendar, so it’s super convenient.
  5. Apple Calendar (iCal): For Apple enthusiasts, iCal seamlessly integrates with your Apple devices. This handy tool allows you to create, share, and even categorize events with colors. It syncs across your devices and can also integrate with other calendar services.
  6. Zoho Calendar: Zoho Calendar isn’t just a standalone product, it’s part of an extensive suite of productivity tools offered by Zoho. You can schedule and share events, manage multiple calendars, and it integrates well with other Zoho apps as well as external calendars.
  7. TimeTree: TimeTree is like a communal bulletin board for your schedule. It allows you to create shared calendars where everyone can add, view, and edit events. It’s especially useful for coordinating schedules among family members or project teams.


Q: What’s a calendar? A: A calendar is a magical system used for measuring time, invented way back when people realized “eventually” and “sometime” were too vague for arranging meetings.

Q: How does a calendar work? A: Like a diary that future you wrote. A calendar helps you keep track of days, weeks, months, and years. It’s like a roadmap for your time, without the annoying “recalculating” from your GPS.

Q: How do I add an event to my calendar? A: It’s a piece of cake! Choose your date, time, and bam, you’ve got an event. Just remember, your calendar won’t actually bake the cake for you on that date.

Q: Can I share my calendar with others? A: Yes, you can! It’s like giving people a window into your world. But luckily, they can’t see your messy desk, just your well-organized schedule.

Q: Can I sync my calendar with other calendars? A: Absolutely! Your calendar can have playdates with other calendars. It’s like your calendar joining a club where they all share the best events.
