When
You need the weekday of a date, a date N days later (ticketing deadline, minimum stay), local time in another city, the length of a journey, a quick sum, or a unit conversion.
Steps
| # | Entry | What it does | Why |
|---|---|---|---|
| 1 | DD | Current system day, date and time. | Amadeus runs on its own clock; deadlines follow it. |
| 2 | DD19JUL26 | Weekday of a date. | "Is the 19th a Sunday?" |
| 3 | DD12APR/21 · DD15MAR/-35 | Date 21 days later · 35 days earlier. | Advance-purchase and ticketing deadlines. |
| 4 | DD3MAR/15APR | Number of days between two dates. | Minimum / maximum stay rules. |
| 5 | DDPAR · DDPAR1800/NYC | Current time in Paris · 18:00 Paris in New York time. | Call an airline office at the right hour. |
| 6 | DDFRA2125/SYD0535+2 | Elapsed journey time (leave FRA 21:25, arrive SYD 05:35 two days later). | True travel time across time zones for the client. |
| 7 | DF 50;40 · DF 40/20 · DF 20*30 · DF 20-10 | Add · divide · multiply · subtract. | Quick sums without leaving the screen. |
| 8 | DKKM80 · DKMK50 · DKKP9 · DKPK20 | km→miles · miles→km · kg→lb · lb→kg. | Bag allowances in pounds, distances in miles. |

The answer shows the result; DD with a date shows the weekday.
Traps
- Year:
DD19JUL05means 2005. Add the year when it is not the coming date. - Flight times in displays and PNRs are local times at each airport — use step 6 for the real duration, never subtract local times by hand.
- In
DF,;means plus.
