Calendar bots put your schedule where you already spend the day: add an event by message, get a morning summary, share a meeting with a group, convert a time for a colleague abroad. Some are full calendars, others connect to Google Calendar you already use.

Every bot got the same week of events, including a recurring one, a meeting with a time zone and an all-day reminder. We checked how fast an event can be added by text, whether the bot understands natural language dates, how the morning digest looks, whether events sync to an external calendar in both directions and how sharing with a group works. Access scopes requested from Google were compared with what the bot actually needs.
Calendar (@calendar0bot) is a calendar of its own, opened as a Mini App, with two-way Google Calendar sync and support for Apple and other CalDAV calendars. Google Calendar Bot and Task Scheduler Bot are bridges: they read and write your existing Google Calendar, which suits people whose work lives there. Pick the bridge if colleagues send invites to your Google account, the standalone calendar if Telegram is where your plans start.
The convenience is in typing "dentist Thursday 15:00" and having it land in the right place. Test the bot with your own phrasing, in your language, with a date next month and with a repeating event; natural-language parsing is where bots differ most. A morning digest message is worth turning on: it replaces opening the calendar app.
Calendar keeps a shared calendar for a family or team chat. For a meetup where people sign up, Mitup shares one card that friends join with a tap and reminds each of them in their own time zone. For a one-off conversion, Timezone Bot answers "/convert 3PM GMT to PST" in a second and can count down to an event. Reminders without a calendar are a separate rating; habit trackers too.

Calendar keeps one shared calendar for a group chat once you invite the bot; for a meetup with sign-ups, Mitup shares a card that friends join with a tap.
