# Extend Date Range

This section introduces how to configure metrics such as DAU/WAU, daily payment amount/monthly total payment amount ratio via "Extend Date Range" in Events.

By default, the data of a displayed date is based on the selected events on this date; for example, the DAU of January 7 is calculated based on the number of users who triggered the login event on this day.

There are also some special metrics. For example, DAU/WAU ratio is used to measure user stickiness, and is defined as the number of logins in one day/the number of logins in the last 7 days. If the displayed date is also January 7, then the numerator of DAU/WAU ratio counts the number of logins on January 7, while the denominator needs to calculate the number of logins from January 1 to January 7. In other words, "Extend Date Range" feature enable you to analyze a time frame beyond the displayed date.

Currently, Event Analysis supports the following five ways to extend the time frame.

Options Logic Description
Last The N days past before the displayed date, not including the displayed date.
Recent The last N days before the display date, including the displayed date.
Whole week The whole week including the displayed date, with customizable week start date.
Whole month The whole month including the displayed date.
Range A time frame based on the displayed date. A negative number represents N days before the displayed date; a positive number represents N days after the displayed date; and 0 represents the displayed date.

In addition to the user stickiness metric, you can also calculate period-over-period data about analysis metrics by extending time frame and display the period-over-period trend in these metrics.

This feature also enables quick view of the percentage of daily paid amount in monthly payment and cumulative trend display with a cumulative chart.


When Extend Date Range is enabled, the analysis granularity is locked as "day" and cannot be adjusted.
