“What’s on the schedule today?” “How many days until the next anniversary?” LightCal² is a minimalist calendar app that brings multiple features together in one clean experience. View detailed date information at a glance. Comprehensive schedule management is built in. 【Countdown】 See exactly how far every special day is from today. “We’ve known each other for over two thousand days…” “Only a few days left before the exam…” “My child’s birthday is coming up — time to prepare a gift.” Whether counting down to the future or counting up from the past, every meaningful moment stays clear and visible. 【Date Badges】 Anchor meaningful moments directly onto specific dates. Add special markers to days that matter — small signs of a life well lived. “Maybe this would be perfect for marking work shifts…” “Our holiday schedule is a little different — better mark it.” Every ordinary day deserves to be taken seriously. With a clean and thoughtful design, LightCal² brings a sense of ritual to your time. More features are already on the way.
