This plugin works the range out from your actual pattern— open weekdays, preparation time, carrier transit days and the official holiday calendar— and displays it on the product page before checkout, stated as an estimate, never a promise. **How it works** * You choose a holiday calendar: **UK bank holidays** (official GOV.UK data, per division — England & Wales, Scotland, or Northern Ireland) or **Japanese national holidays** (generated from the statutory rules). * You set your store’s open weekdays, any extra custom closed dates, an order cut- off time, a preparation time in business days, and a transit range in carrier days. * On each product page the plugin counts forward from the moment of viewing: orders before the cut-off start preparation the same business day; later orders start on the next business day. Preparation and transit skip closed days, weekends and holidays on the correct calendar. * The calculation runs **in the visitor’s browser at view time** (in your site’s timezone), so the dates stay correct even behind full-page caches and CDNs — including right after the cut-off and across daylight-saving changes. Without JavaScript no dates are shown, rather than risk showing a wrong one. * The result is displayed as a **range with its basis** (“Based on UK bank holidays( England & Wales). Estimate — not a guarantee.”), plus a live “order within X hrs Y mins” countdown when the cut-off is still ahead. **Built-in safety** * If a calculation would run past the end of the bundled calendar data, the estimate is **hidden entirely** and the failure is flagged in wp-admin, instead of showing a date the data cannot support. * A **simulator** (Tools Delivery Date Simulator) runs the exact storefront calculation— for any order moment, product and (with Pro) destination — and shows the dispatch date, the range, the effective values used, and the day-by-day walk with reasons, including holiday names. * A **status panel** on the settings page shows the calendar coverage with advance warnings before the data runs out, and settings can be **exported/imported** as JSON. * The plugin makes **no external calls**, stores **no personal data**, and does not read or write orders. All computation happens locally with the bundled calendar data. **Calendars included** * United Kingdom: official bank holidays from GOV.UK (https://www.gov.uk/bank-holidays. json), 2025–2028, for England & Wales, Scotland and Northern Ireland — including substitute days. * Japan: national holidays 2025–2028 generated from the rules of the Act on National Holidays, including substitute holidays (振替休日) and citizens’ holidays (国民 の休日). A Pro add-on (sold separately, outside wordpress.org) adds per-product and per-category preparation times, per-shipping-zone transit adjustments, a Royal Mail carrier-holiday layer for the UK, a customer-facing calculation breakdown, and display customisation. ## Screenshots [⌊The estimate on a product page (UK calendar), with its basis line and cut-off countdown.⌉⌊The estimate on a product page (UK calendar), with its basis line and cut-off countdown.⌉[ The estimate on a product page (UK calendar), with its basis line and cut-off countdown.

Upload the `soroban-delivery-dates` folder to `/wp-content/plugins/`, or install the zip via Plugins Add New Upload. 2. Activate the plugin. 3. Go to WooCommerce Delivery Dates and choose your calendar, open days, cut-off time, preparation and transit times. 4. Check a scenario under Tools Delivery Date Simulator. 5. The estimate appears on single product pages automatically. You can also place it anywhere with the `[soroban_delivery_estimate]` shortcode. ## FAQ ### Are the dates a guarantee? No. The plugin always presents dates as an estimated range with its basis stated, and never as a guaranteed delivery date. Weather, carrier delays and other factors outside the calculation can still change the actual arrival day. ### Which calendars are supported? UK bank holidays by division (England & Wales, Scotland, Northern Ireland), from official GOV.UK data, and Japanese national holidays generated from the statutory rules. Each store uses one calendar. ### What happens when the calendar data runs out? The bundled data covers 2025–2028. If a calculation would need dates beyond the coverage, the estimate is hidden and an admin notice records the fail-safe event. Update the plugin to receive newer calendar data. ### Does the plugin phone home or track customers? No. There are no requests to third-party services and no analytics. The only data stored is your settings and the fail-safe state record (reason and timestamps only). The per-product calculation inputs endpoint answers using the visitor’s own WooCommerce session (for shipping-zone rules) and stores nothing. ### Does it work with page caching or a CDN? Yes. Product pages contain no pre-calculated dates; the estimate is computed in the visitor’s browser when the page is viewed, using a cacheable configuration document whose URL changes whenever settings change. Per-visitor inputs are fetched with a private, no-store request. ### Does it need JavaScript? On the storefront, yes: dates are calculated in the browser so they are correct at the moment of viewing. Without JavaScript, no dates are displayed (a short neutral note appears instead). wp-admin (settings preview and simulator) works without JavaScript. ### Who can change the settings? Anyone with the WooCommerce shop-management capability (Administrators and Shop Managers). Viewing and saving use the same capability. ### Can I set different preparation times per product? Not in the free version — one store-wide preparation time. Per-product and per-category preparation times are part of the Pro add-on. ### Does it work with HPOS (custom order tables)? Yes. The plugin declares HPOS compatibility, and it does not read or write order data at all. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Soroban Delivery Dates for WooCommerce” is open source software.

The estimate now displays correctly with both“ Plain” and “Pretty” permalink settings. No settings or data are changed by this update. #### 1.1.2 * Renamed: the plugin is now “Soroban Delivery Dates for WooCommerce” (slug: soroban- delivery-dates), with all internal prefixes renamed to match. The plugin was never publicly released under the old name, so no settings migration is involved. * Hardened: the calculation-breakdown HTML hook output is now passed through wp_kses_post() before display, and the admin preview is sanitised at the output point. * Hardened: the per-product REST endpoint now answers only for products that are publicly viewable; draft, private, password-protected and catalog-hidden products return the same 404 as a missing product. #### 1.1.1 * Release preparation: re-verified against the current stable WordPress and WooCommerce releases (see the header’s “Tested up to”). Minimum PHP raised to 8.0 — PHP 7.4 no longer receives security fixes from the PHP project (8.2 or later is recommended). * A translation template (.pot) now ships in the /languages folder. #### 1.1.0 * Cache-safe storefront rendering: estimates are computed in the visitor’s browser at view time (site timezone, DST-aware), so full-page caches and CDNs can no longer serve stale dates. Per-visitor shipping-zone inputs are resolved privately per session. * Fixed: Shop Managers could open the settings page but not save (capability mismatch between the page and the Settings API registration). Viewing and saving now both use manage_woocommerce. * Fixed: the fail-safe admin notice never cleared after recovery. Failures, ongoing problems and recoveries are now tracked as distinct states, with a daily health check. * The simulator now uses the same calculation path as the storefront (including all Pro rules) and can test a specific product and destination zone; it shows the effective values and which rules matched. * Settings page: 5-minute setup guide, status panel with calendar-coverage expiry warnings, live preview, and settings export/import. * Verified PHP/JS calculation parity (18 scenarios, including DST weekends, cut- off boundaries in BST, Scotland carrier exceptions). #### 1.0.0 * Initial release. * UK bank holidays (GOV.UK, three divisions) and Japanese national holidays (statutory rules), 2025–2028. * Business-day preparation counting with order cut-off, carrier-day transit range, fail-safe hiding beyond calendar coverage. * Admin simulator with day-by-day walk. ## Meta * Version **1.1.3** * Last updated **7 hours ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **7.1.4** * PHP version ** 8.0 or higher ** * Tags * [delivery date](https://wordpress.org/plugins/tags/delivery-date/)[estimated delivery](https://wordpress.org/plugins/tags/estimated-delivery/) [woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/soroban-delivery-dates/advanced/) ## Ratings No reviews have been submitted yet.
