Amadeus DD Command: Time & Date Calculations

A complete guide to the DD command in Amadeus — how to calculate time differences, local times, and dates directly from the terminal.

DD is the Amadeus GDS command used to calculate time differences, local times, and dates.

Category: Time & Date Calculations.

It allows you to quickly check local time, time differences between cities, and date calculations directly in the Amadeus terminal. DD works on a wide range of practical scenarios — from confirming what time a passenger will arrive after a long-haul flight, to checking which day of the week a departure falls on. Entering DD on its own also displays the system time, current day, and date.

Calculate the local time in Madrid:

DDMAD

This displays the current local time in Madrid (MAD). Use it to confirm the local time at a destination before calling a customer or contacting a supplier in another country.

Calculate the time in Madrid when it is 15:00 in Miami:

DDMIA1500/MAD

This displays the corresponding time in Madrid when it is 15:00 in Miami. It is useful when coordinating calls, transfers, or onward connections across time zones.

Calculate the time difference between London and Los Angeles:

DDLON/LAX

This displays the time difference between London (LON) and Los Angeles (LAX). Use it to explain to a customer how much time they will gain or lose on a flight between the two cities.

Determine the day of the week for a specific date:

DD19JUL

This displays which day of the week the 19th of July falls on. Use it when a customer wants to travel on a specific day, or when checking that a holiday or event falls on the date they think it does.

• DD can be used for both time and date calculations.
• You can calculate elapsed time, time differences, and dates before or after a specific date.
• DD by itself displays the system time, current day, and date.

Use DD whenever you need to quickly calculate local times, time differences, or travel-related dates in the Amadeus terminal. Typical scenarios include:

• Confirming what time a passenger will arrive at their destination after a long-haul flight.
• Calculating how much time they will gain or lose between two cities.
• Explaining the local time at a destination to a customer before they travel.
• Checking the day of the week for a specific travel date.
• Coordinating calls or transfers with a supplier in another time zone.
• Confirming whether a customer will arrive on the same day, the next day, or the previous day.
• Planning dates that fall before or after a specific departure date.

A typical session using DD might look like this:

• Retrieve the PNR with RT or open availability with AN.
• When a time or date question arises, enter the appropriate DD entry — for example DDMIA1500/MAD or DDLON/LAX.
• Note the result and share it with the customer if needed.
• Add a remark to the PNR with RM if the time or date information should be documented.
• Continue with pricing, ticketing, or any other required step.

• DD → calculates time differences, local times, and dates.
• DK → converts units, temperatures, and decimal values.
• GDS calculator guide → an overview of the calculation and conversion tools available in the GDS.
• DM → displays minimum connecting time for a connection.
• DO → displays detailed flight information including departure and arrival times.
• RTIM → displays the full itinerary with segment times.
• RH → displays the PNR history, including time-related changes.

The distinction matters: DD handles time and date calculations; DK handles unit and decimal conversions; DO and RTIM show flight times from the itinerary. Use DD when you need to answer a time or date question independently of the booking.

Important: DD displays time and date calculations based on standard time zone data. It does not account for every irregular time zone or daylight saving rule automatically — always confirm the final arrival time with the airline or by checking the flight details with DO.

For itinerary times and connections already in the PNR, use RTIM to see the segment times and DM to verify connecting times.
