Min Calendar

inputwp

Availability Datepicker by <a href="https://www.inputwp.com/" rel="nofollow ugc">InputWP</a> is a booking calendar and date time picker plugin that turns any text field into a smart availability datepicker. Define your business hours, booking type, and availability rules — the calendar enforces them automatically on the frontend. Works with Contact Form 7 via a simple CSS selector, with no code required on your end.
<h4>Perfect For</h4>
<ul>
<li>Doctor / Medical clinic — Fixed 30-minute appointment slots, Monday–Friday, 24-hour minimum notice, 60-day booking window.</li>
<li>Salon & Beauty — Fixed 60-minute sessions, Monday–Saturday, 2-hour advance notice, 30-day booking window.</li>
<li>Hotel / Vacation Rental — Day Based mode, check-in and check-out date selection, minimum 2-night / maximum 30-night stay, 365-day booking window.</li>
<li>Car Rental — Flexible Range, pickup and return with date and time, 4-hour minimum / 7-day maximum, every day, 90-day booking window.</li>
<li>Equipment Rental — Flexible Range, overnight to multi-day rentals, 12–72-hour duration, 60-day booking window.</li>
<li>Meeting Room — Flexible 1–8-hour bookings, Monday–Friday, 15-minute buffers between slots, 30-day booking window.</li>
<li>And anyone who runs appointments, reservations, or rentals and needs to show live availability on their booking form.</li>
</ul>
<h4>Works with Contact Form 7</h4>
Availability Datepicker integrates with Contact Form 7 (and any other form plugin) through a CSS selector. Add a text field to your form, copy the CSS class from the Integration panel, and paste it into the field’s class setting. No shortcodes or custom code needed.
Follow the step-by-step guide for <a href="https://www.inputwp.com/about/date-and-time-picker-field-on-contact-form-7/" rel="nofollow ugc">Contact Form 7</a> or <a href="https://www.inputwp.com/about/date-picker-in-divi-contact-form/" rel="nofollow ugc">Divi</a> to connect your date picker field in minutes.
<h4>Three Booking Types</h4>
Choose the booking type that matches how your business operates:
<ul>
<li>Fixed Time Slots — Guests pick a specific time slot (e.g. 9:00 AM – 10:00 AM). Ideal for appointments, consultations, and classes. Uses a single date and time field.</li>
<li>Day Based — Guests pick a check-in date and a check-out date. Ideal for hotels, B&Bs, and vacation rentals. Uses two separate date fields.</li>
<li>Flexible Range — Guests pick a start date+time and an end date+time. Ideal for car and equipment rentals, meeting rooms, and multi-hour bookings. Uses two separate date+time fields.</li>
</ul>
Six Quick Setup Presets let you pre-fill all availability settings for the most common scenarios in one click.
<h4>Advanced Availability Settings</h4>
The availability calendar is driven by a comprehensive set of rules you configure in the admin panel:
<ul>
<li>Business Hours — Enable or disable each weekday independently. Add multiple open time ranges per day to model morning and afternoon shifts.</li>
<li>Availability Window — Control how far ahead booking is open: dynamically (X days from today) or within a fixed predefined date range.</li>
<li>Slot Interval — Set the gap between available time slots: 15, 30, or 60 minutes.</li>
<li>Minimum Notice — Require a minimum lead time before a slot can be booked (e.g. 24 hours in advance).</li>
<li>Buffers — Add preparation or cleanup time before and after each slot to prevent back-to-back bookings.</li>
<li>Min/Max Bookable Days — Set the shortest and longest allowed stay lengths (Day Based mode).</li>
<li>Min/Max Duration — Set the shortest and longest allowed rental or booking period (Flexible Range mode).</li>
<li>Blocked Dates — Mark specific dates as unavailable: holidays, closures, one-off exceptions.</li>
<li>Allowed Date Exceptions — Open a normally-closed date with custom hours (e.g. a special Saturday opening).</li>
<li>Live Admin Preview — See how the calendar looks with your current settings before saving.</li>
</ul>
