There are plenty of free and paid economic release calendars available, which can be scraped for historical release data or accessed through a proprietary API. Since the focus of this section is utilizing economic release data in trading, we will skip the details of accessing historical data, but it is quite straightforward. Most common economic release calendars look like this:

As we discussed earlier, the date and time of releases are set well in advance. Most calendars also provide the previous year's release, or sometimes the previous month's release. The Consensus estimate is what multiple economists or firms expect the release to be; this is generally treated as the expected value of the release, and any large misses from this expectation will cause large price volatility. A lot of calendars, in addition, provide a Forecast field, which is the calendar provider's expected value for that economic release. At the time of writing, https://tradingeconomics.com/, https://www.forexfactory.com/, and https://www.fxstreet.com/ are some of the many free and paid economic calendar providers.
