See your dates, organize your plans and make room for what matters. Persian Calendar brings Persian (Solar Hijri), Gregorian and Islamic (Lunar Hijri) dates together with occasions, notes, reminders and planning tools.

Optional AI planning assistant

Chat with the assistant for travel, exercise, daily or weekly planning ideas. Share your departure city, destination, transport and preferences, then answer follow-up questions to refine the plan. Read the written proposal first, review the suggested items and confirm which ones to add as calendar notes or reminders.

Planning around your routine

Set your usual departure city, travel transport, working days and hours, commute time and activity buffers. Review warnings about conflicts with existing reminders before saving. Preview changes to local notes and reminders, and undo an assistant-applied change when the affected items have not been changed again.

Calendar tools without an AI key

Find free time, the next non-Friday Iran public holiday and four-day break opportunities using the app's bundled calendar data. These tools do not require an AI key. Newly announced holidays may not yet be included.

The AI assistant is optional. AI replies require internet access and your own API key from a supported provider, such as Gemini or OpenRouter. In-app instructions explain how to obtain a key. Your conversation and relevant planning information are sent to your selected provider when you make a request. Availability, quotas and costs depend on that provider. Core calendar features remain available without enabling AI.
