What Calendar does
Calendar, the bot at @calendar0bot, is one of the few Telegram bots that behaves like an actual calendar rather than a reminder list. Its strength is capture: forward a channel post or an invitation, dictate "gym every Friday at 7", send a photo of a ticket or a poster, a PDF, or an .ics file, and it pulls out the title, date, time, place, repeat rule and call link, asking when something is unclear. Several events can arrive in one message, and recurring meetings or yearly birthdays are handled too.
The calendar itself opens as a Mini App with events, intervals and day notes, and it marks public holidays and short workdays. Each morning the bot sends a plan before your first event. You can mention @calendar0bot in any chat to add an event or show your plans without leaving the conversation, or invite it to a family, team or community chat to keep one shared schedule there. For people already on another calendar, the site lists two-way sync with Google Calendar and support for Apple Calendar and any CalDAV service, and there is a small macOS menu-bar companion.
Catalog listings describe the interface in English, Russian, Spanish and other languages. Neither the site calendar-tg.app, which links the bot, nor those listings mention a price.
