Cal24h is an online booking platform that lets you publish event calendars, appointment forms, and catalogues. This plugin embeds any Cal24h organization or event on your WordPress site with just a shortcode or block, while offering a floating button modal for persistent calls to action.
Highlights
<ul>
<li>Gutenberg block with an inspector panel to configure organization, event, language, and appearance.</li>
<li>Shortcode <code>[cal24h]</code> supporting attributes for iframe or floating-button display modes.</li>
<li>Settings page (<code>Settings → Cal24h</code>) to define default values such as organization slug, event slug, language, and colors.</li>
<li>Responsive floating button that opens a customizable modal overlay.</li>
<li>Ready-to-ship translations and language loading for both editor and front end. Included locales: ar, bn_BD, da_DK, de_DE, el, en_US, es_ES, fa_IR, fi, fr_FR, he_IL, hi_IN, id_ID, it_IT, ja, ko_KR, nb_NO, nl_NL, pa_IN, pt_BR, pt_PT, ru_RU, sv_SE, sw, tr_TR, ur, wo, zh_CN.</li>
<li>Paste-friendly slugs: you can paste a full Cal24h URL (e.g., <code>https://cal24h.com/integration/org/event</code>) into settings or shortcode attributes — the plugin extracts the correct organization/event automatically.</li>
</ul>

Among half a dozen of booking plugins, times-lot has been evaluated as the best choice for our small online+face-to-face company activity, and we enjoy using it: + Doing well the job with all essential features, as advertised, easy to configure. + An excellent clear and sound documentation for non expert installation. + A rather cheap and clear price (no complex price "scarfolding"). + The plugin internal php code is really well written up to our best expertise. +++ The development team is really kind and super reactive and effectively helping.Merci beaucoup :)
