Currently we encountered some issue on displaying estimated delivery date.
We followed the API document to send the min/max delivery date and calculated the date by business day.API REF: https://shopify.dev/docs/admin-api/rest/reference/shipping-and-fulfillment/carrierservice
In our case [UPS - 2nd Day Air] for example, the Delivery Timeline is 2 business days.
Hence we send the delivery date by the calculation below:
9/6(Sun) - checkout day (the day shows the checkout rate)
9/7(Mon) - Holiday (Labor Day)
9/8(Tues) - Day 1
9/9 (Wed) - Day 2
9/10 (Thur) - Estimated delivery date (2 days after)
Response date we send:
But at the end Shopify show [4 business days] on the checkout page and the client is confusing why this service needs 4 business day.
Looks like when Shopify didn't consider weekend/holiday when converting the date in to delivery day.Is this a bug in Shopify side or should we send the date calculated base on normal day instead of business day?Thanks a lot in advanced for any suggestions!
