# Calendars for React and Tailwind

> A calendar has to stay readable when a day gets busy. Look at how each one handles overlapping events, long titles and the switch between views. Small screens need real thought, because a month grid gets tight fast. Install one as code you own, then connect it to your own events or bookings. Today should always be easy to find, whatever the view.

- [Calendar](https://layro.dev/@preetsuthar17/calendar.md): A date grid for selection with sliding months (`npx layro-cli add @preetsuthar17/calendar`)

## About

Calendar components show dates in a grid. Small ones are month views for picking a day or a range, larger ones are scheduling views by day, week or month with events placed in time slots, and some add availability, bookings or a timeline of resources.

Get the date logic right before the looks: time zones, the first day of the week, locales and ranges that cross months. Make the grid work with the arrow keys, label each day fully for screen readers and show which days can't be chosen.

## Frequently asked questions

### Which React calendar library should I use?

react-day-picker is the base of many date pickers, including shadcn's. For scheduling views with events, look at FullCalendar or a headless option you style yourself.

### How do I build a month calendar in React?

Work out the first day shown, which can belong to the previous month, then render six rows of seven days. A date library such as date-fns makes the arithmetic reliable.

### How do I select a date range on a calendar?

Store a start and end date, set the start on the first click and the end on the second, and highlight the days between. Swap them if the second date comes first.

### How do I handle time zones in a calendar?

Store dates in UTC or as plain dates without time when only the day matters, and convert to the person's zone for display. Most bugs come from mixing the two.

### How do I make a calendar accessible?

Use a grid role, let arrow keys move between days and Page Up and Down change months, and give each day a full label such as Monday 3 March.

### What is the difference between a calendar and a date picker?

A calendar is the grid of days. A date picker wraps a calendar in a field and a popover so people can type or pick a date for a form.

### How do I show events on a week view?

Position each event by its start time and duration within the day's column, and place overlapping events side by side with reduced width.
