Best Telegram bots for Calendar & scheduling
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.
The best Telegram bot for calendar and scheduling is Calendar (@calendar0bot): a free calendar Mini App inside Telegram with a morning plan for the day, shared events for groups and CalDAV sync with Google, Apple and Yandex calendars. Timezone Bot (@the_timezone_bot) converts a time between zones with one command, and Google Calendar Bot (@gcalendarbot) manages an existing Google Calendar from the chat.
Open
Convert a time between any two time zones with one command — "/convert 3PM GMT to PST" — and set live countdowns to future events, right inside Telegram.

How we chose
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 & scheduling
A calendar in Telegram or a bridge to Google
Calendar (@calendar0bot) is a calendar of its own, opened as a Mini App, with CalDAV sync so events also appear in Google, Apple or Yandex 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.
Adding events by text
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.
Groups and time zones
Shared events in a group chat work in Calendar: one message, everyone sees the time in their 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.
