Delivery Date Picker

The problem

Shoppers decide whether to buy partly on when an item will actually arrive, and a cart page that says nothing about that is asking them to guess. Most stores either leave the question unanswered until the confirmation email, or hardcode a generic "delivery in 3 to 5 business days" message that quietly becomes wrong the moment a shipping method changes or a holiday falls in the middle of the week.

How it works

This extension replaces that guess with a real estimate, calculated from rules a merchant actually sets. Each rule defines:

• A cutoff time, past which an order counts as placed the next business day
• A lead time in business days before the order ships
• An optional delivery window (a range of days rather than a single date)
• The specific shipping method the rule applies to, by carrier and method code

When a shopper on the cart page selects a shipping method, the estimate updates immediately, calculated from the current time in the store's own timezone against that method's own cutoff and lead time.

Holidays and blackout days

Delivery dates are only useful if they account for the days a store genuinely cannot ship on. Weekly blackout days, no dispatch on weekends for example, are set per rule, and a single shared holiday calendar covers company wide closures without needing to be re-entered on every rule that uses it. Every date the module produces already accounts for both, so an estimate spanning a public holiday correctly pushes the delivery window out rather than quietly showing a date nothing will actually ship on.

Multi store support

Because rules can be scoped to individual store views, a store selling into more than one country or region can run different cutoff and lead time rules for each, without needing separate installations or manual overrides at checkout.

What the shopper sees

The result is a delivery estimate a shopper can actually trust, calculated the same way your warehouse and courier partners actually work, not a generic promise that happens to be right some of the time.
