| 1 | +# Chronos — Weekly Scheduler |
| 2 | + |
| 3 | +Chronos is built around a simple idea: you have a list of things you need to do, and you should be able to drag them straight onto your week and schedule them — no friction, no fuss. Start with your tasks on the right, drag them onto the calendar on the left, and your week plans itself. |
| 4 | + |
| 5 | +A fully offline weekly planner that lives in a single HTML file. |
| 6 | +No accounts. No server. No dependencies. Just open and schedule. |
