You can use the LSEG Data Library for Python to retrieve an economic indicator’s next release date by passing the relevant Refinitiv Instrument Code to the get_data function and requesting the necessary fields.

The ECI_ACT_DT field contains the confirmed date when new data will be released. This is the preferred field as it represents the official release schedule. However, this field may not be updated immediately after a release, causing it to show a past date until the next schedule is entered into the system.

The NDOR_1 field is a forward-looking value that always contains the next scheduled release date. This serves as our fallback when ECI_ACT_DT is stale or in the past.

Here’s how to retrieve the next release date for the US Consumer Price Index, a monthly inflation indicator released by the US Bureau of Labor Statistics:

ld.get_data(
    "USCPI=ECI",
    fields=["ECI_ACT_DT", "NDOR_1"],
)
Instrument ECI_ACT_DT NDOR_1
0 USCPI=ECI 2025-10-24 2025-11-13
