How to Use an Economic Calendar Before and After Data Releases

Check time zones and reference months in an economic calendar and build records before and after releases. Separate forecasts, actuals, and revisions, and confirm official schedules.

An economic calendar is a tool for planning what information to check and when, rather than predicting releases. Align the displayed time zone and reference period, then record forecasts, actual figures, and revisions to previous values separately. Schedules can change, so reconfirm important releases against the releasing agency’s official schedule.

Select releases connected to your research purpose

Following every release from every country makes it difficult to distinguish important information. First identify the channels relevant to your company analysis, such as input costs, export demand, or interest burdens, then select the corresponding indicators. The Investing.com economic calendar can narrow material by date range, country, category, and other filters. Importance ratings help allocate attention, but they do not always match the indicators important to your company analysis. Once you choose an indicator, decide which components to examine as well as the headline figure, so your interpretation does not become fixed on a single number at release time.

Release time and reference month are different information

The calendar date shows when a release is scheduled, while the statistics may describe an earlier period. Check the displayed time zone and use the offset applicable on that date when converting to Korean time. Overseas daylight saving time means you should not mechanically apply one offset throughout the year. For U.S. CPI, the BLS official schedule separately provides the reference month, release date, and release time. Retaining all three when adding the event to your calendar clarifies what figure is coming and when. Recheck the official page for schedule changes before the release.

Record revisions separately from interpretation after the release

A new figure being above or below forecast is different from interpreting it as favorable for stocks. Inflation, employment, and business-cycle indicators can simultaneously give different signals. After a release, organize the forecast-versus-actual difference, revisions to previous values, and component changes in that order. If recording price reactions, fix the observation window so comparisons are possible. Do not mix a few minutes of movement with a full day’s change. Retaining your interpretation before and after the release separately reduces the tendency to believe, after seeing the outcome, that you knew it all along.

Worked example

Hypothetical example: If a month-over-month indicator has a forecast of 0.2%, an actual value of 0.1%, and a previous value revised from 0.3% to 0.2%, record the three facts separately. The current actual is 0.1 percentage points below forecast, and the previous figure was also lowered by 0.1 percentage points. Do not add them together and write that “this release disappointed by 0.2 percentage points.” Store the prerelease baseline separately from the postrelease revision history to enable next month’s comparison.

What to check

  • Is the selected indicator connected to a business variable?
  • Have you recorded both the displayed time zone and reference month?
  • Have you checked the official schedule for changes?
  • Have you recorded the current figure separately from revisions to the previous value?
