Features of Dayter
Universal Countdown Calendar
Consolidate every important date from all areas of your life into one master calendar. Track birthdays, work deadlines, vacations, and personal goals simultaneously. The live, updating countdowns provide an instant, real-time view of exactly how much time you have left, eliminating constant mental calculation and keeping urgency and anticipation front and center.
Intelligent Recurrence & Reminders
Go beyond one-time events with powerful, set-and-forget recurrence options. Configure events to repeat yearly, monthly, weekly, or even daily. This automates the tracking of birthdays, anniversaries, weekly meetings, bill payments, and daily habits. The system handles the repetition for you, ensuring you're always prepared for what's next without manual re-entry.
Timezone-Aware Event Scheduling
Plan and track events accurately across the globe. Dayter allows you to set the specific timezone for each event, ensuring countdowns and reminders are perfectly synchronized for international trips, virtual meetings with remote teams, or tracking holidays in different countries. This eliminates timezone confusion and guarantees you're always on time, anywhere.
Visual Progress Tracking & Customization
Stay motivated with clear visual feedback. Dayter displays a progress percentage for your countdowns, showing you exactly how far you've come toward your target date. Further personalize events with custom cover images and descriptions, turning a simple date into a rich, visual milestone that keeps you engaged and focused on your goals.

Frequently Asked Questions
Is Dayter really free to use?
Yes, Dayter is a free online countdown app. You can start creating countdowns, using the calendar, and setting reminders immediately without any cost. This makes it an accessible tool for anyone looking to quickly organize their key dates and timelines without financial commitment.
Can I share my countdown calendar with others?
Absolutely. Dayter is built for both individual and collaborative use. You can share your calendar views with family members, friends, or team members to ensure everyone is synchronized on important dates, from group project deadlines to shared vacation plans, enhancing coordination and collective anticipation.
How does the recurrence feature work?
When creating or editing an event, you can select a recurrence pattern: No Repeat, Yearly, Monthly, Weekly, or Daily. Once set, Dayter automatically generates the future instances of that event. For example, a yearly event for a birthday will reappear on your calendar each year without you having to manually add it again.
What happens when a countdown reaches zero?
When the countdown timer hits zero, the event is marked as live or completed. You will have received reminders leading up to the date based on your settings. For recurring events, the system will automatically reset the countdown for the next instance (e.g., next year's birthday), so your tracking continues seamlessly.
