No cron jobs, no weekly updates, no remembering to turn it off. Connect your site to [Shamor](https://shamor.app) in under 5 minutes. From that point on, your site displays a beautiful, customizable block screen at candle-lighting time and comes back online automatically when Shabbat ends — week after week, holiday after holiday. **Beyond your website — full community coverage:** Shamor doesn’t stop at your WordPress site. The same account also automatically locks and unlocks your **WhatsApp groups**, **Telegram channels**, and **Discord servers** every Shabbat and Yom Tov — so you’re fully covered across every community you run. Your website, your chat groups, and your social communities all go quiet at candle-lighting and come back at Havdalah, automatically, with no manual work. **Perfect for:** * Jewish businesses and e-commerce stores that want to observe Shabbat online * Synagogues and community organizations managing websites, WhatsApp, Telegram, or Discord * Torah content sites, Jewish news, and blogs * Any Jewish community leader who wants every platform to reflect their values #### How It Works 1. Start your 7-day trial at [shamor.app](https://shamor.app) and add your website 2. Install this plugin and paste your API key 3.

Two separate endpoints are used: **1. Shabbat blocking status** (`https://shamor.app/api/shabbat-status`) Fetches whether your site should currently be blocked and the weekly schedule of times. *** What is sent:** your site key (an opaque token you created in the Shamor dashboard) and, for visitor-timezone modes, the visitor’s IANA timezone string (e.g. `America/ New_York`). No names, emails, or IP addresses are transmitted. * **When:** once per week server-side (PHP) to cache the schedule; once per browser session from the visitor’s browser when using Visitor’s Time or Stricter modes. **2. Shabbat times widget** (`https://shamor.app/api/widget-times`) Fetches candle- lighting and Havdalah times for the selected city. No Shamor account is required for this feature. * **What is sent:** the selected city’s latitude, longitude, timezone, candle-lighting offset, and your WordPress site’s home URL (to allow the Shamor admin to see which sites have the widget installed). No visitor data is transmitted— this call is made server-side from your WordPress server. * **When:** once per city per week, cached in a WordPress transient until one hour after Havdalah. **Service home:** [https://shamor.app](https://shamor.app) **Privacy policy:** [https://shamor.app/privacy](https://shamor.app/privacy) **Terms of service:** [https://shamor.app/terms](https://shamor.app/terms) ## Blocks This plugin provides 1 block. * Shabbat Times 🕯️ ## Installation 1.

Yes, an account at [shamor.app](https://shamor.app) is required — you can start with a 7-day free trial, no credit card needed. The API key links your WordPress site to your Shamor configuration. ### Which holidays are covered? All major Jewish holidays: Rosh Hashana, Yom Kippur, Sukkot, Shemini Atzeret, Simchat Torah, Pesach, Shavuot, and regional holidays (Yom Ha’atzmaut etc.) — based on Hebcal data. ### Can I customize the block screen? Yes — you can set a custom logo, heading, message, background color, text color, and choose which sections (zmanim, parasha, powered-by) to show. ### Will bots and search engines be blocked? No — common crawlers (Googlebot, Bingbot, etc.) always pass through so your SEO is not affected. ### What happens if Shamor’s server is unavailable? The plugin fails open — your site stays accessible. A local WordPress transient cache stores the last known status. ### Is JavaScript required? Only for “visitor’s time” and “stricter” blocking modes. The default “owner’s time” mode works entirely in PHP with no JS dependency. ### Does Shamor work for WhatsApp, Telegram, and Discord too? Yes — Shamor is a full community platform. The same account that protects your WordPress site can also automatically lock and unlock your WhatsApp groups, Telegram channels, and Discord servers every Shabbat and Yom Tov. Connect them all from your [Shamor dashboard](https://shamor.app). ### Does the Shabbat Times Widget need a Shamor account? No. The widget fetches times from shamor.app, which handles everything server-side. No account, no API key, and no Shamor subscription is needed. ### How do I use the shortcode? Add `[shamor_times]` to any post, page, or widget area. You can pass optional attributes:`[ shamor_times city="new-york" style="card" lang="en" show_parasha="1"]`. See the full attribute list in the block editor sidebar. ### Does the Elementor widget work without Elementor Pro? Yes — the Shamor Elementor widget works with the free version of Elementor (version 3.0 or higher). ### How many cities are available in the widget? 18 built-in presets: Jerusalem, Tel Aviv, Bnei Brak, Haifa, New York, Los Angeles, Miami, Chicago, Toronto, Montréal, London, Paris, Antwerp, Amsterdam, Melbourne, Sydney, Johannesburg, and Buenos Aires. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Shamor — Shabbat & Holiday Site Blocker” is open source software.
