Plan your month with a calendar that feels like paper. GCalendar Lite brings appointments, holidays and local calendar information into one clear monthly view. YOUR MONTH, AT A GLANCE • See your selected day, the rest of its week and the rest of the month in one agenda. • Search event titles, locations and notes directly on the home screen. • Add and edit events, copy an appointment or reuse a saved event template. • Switch between saved calendar groups for work and personal plans. A CALENDAR FOR YOUR REGION Choose holiday calendars for Japan, China, Taiwan, South Korea, Vietnam, Malaysia, Indonesia, India, the United States, the United Kingdom, Germany, Brazil and Russia. Country and interface language can be changed separately. Choose a supported state or region where available, and set the first day of the week to suit you. PAPER, COLOR AND A LITTLE MOVEMENT Enjoy a different background each month, artwork inspired by each region, color-coded date cells and a deep navy dark mode. Tap a date for a compact detail popup, or swipe to turn the page like a book. An expanded display can show two months side by side. Holiday data is bundled through 2037 and can be viewed offline. Unconfirmed dates are labeled as estimates. Lunar festivals, observed holidays and annual workday changes may depend on later official announcements. India uses a central baseline, not every state's leave schedule. Event features require calendar permission. Available events depend on the calendars selected and synced on your iPhone. Lite includes advertising. An optional monthly auto-renewable subscription removes ads; see the current price and billing period in the app. Payment is charged to your Apple Account. The subscription renews unless canceled at least 24 hours before the current period ends. Manage or cancel it in your account's subscription settings.
