Calculations of Blackout Days, Cut Off Time and Delivery Lead Times
The Blackout Days, Cut-off Time, and Delivery Lead Times work together to determine the final delivery date available to customers. Here’s how they interact:
1. Blackout Days
These are the days when delivery is not available (e.g., weekends, public holidays, or custom blackout dates).
The system skips these days when calculating the earliest possible delivery date.
2. Cut-Off Time
This is the daily deadline for processing orders.
Orders placed before the cut-off time are processed on the same day.
Orders placed after the cut-off time are processed on the next business day (skipping Blackout Days).
3. Delivery Lead Time
This represents the minimum processing and shipping time required before the order can be delivered.
The lead time is counted in business days (excluding Blackout Days).
Example: If the lead time is 2 days, the delivery date is calculated by adding 2 business days to the order processing date.
4. How They Work Together
Customer places an order
If it’s before the cut-off time, the order is processed the same day.
If it’s after the cut-off time, the order is processed the next business day.
Blackout Days are skipped
If the order falls on a Blackout Day, it is shifted to the next available business day.
Lead Time is applied
The system adds the specified lead time in business days (skipping Blackout Days) to determine the earliest possible delivery date.
5. Example Calculation of Delivery Days
Example Calculation
Scenario:
Blackout Days: Saturday & Sunday
Cut-off Time: 2:00 PM
Delivery Lead Time: 2 business days
Order placed: Friday at 3:00 PM
Step-by-step calculation:
Order placed after cut-off time → Moved to Monday for processing.
Monday (Processing Day) + 2 business days (Lead Time) → Delivery Date is Wednesday.
