Calendar
Calendar (calendar0bot) is one of the few Telegram bots that behaves like an actual calendar rather than a one-off reminder. You can add an event by writing it in plain language ("team dinner Friday evening"), by uploading an .ics file, a screenshot or a document, or by connecting an existing Google, Apple or Yandex calendar over CalDAV so events stay in sync in both directions instead of living only inside the bot.
Day to day, it sends you a plan each morning listing what is coming up, and /upcoming gives you the same view on demand. It can be added to a group so a team or a household shares one calendar instead of everyone keeping a private one, and it even ships a small macOS companion app via /downloads for people who want a native menu-bar view. The trade-off for that breadth is a slightly less polished, more "indie project" feel than a big-brand product, and the interface stays in English.
