# Time Configuration

Under **Settings → Application Settings → Time Configuration,** admins can control how Tellius interprets and interacts with time-based data across queries, insights, and calendars (especially when dealing with non-standard or fiscal calendars).

### Weekend Date Configuration

**Use weekend date by default**

If enabled, Tellius will use the weekend date as the reference point for time-based calculations (e.g., weekly comparisons, trending by weekends). This is helpful for businesses whose data processing or reporting aligns with weekend cycles.

### Time Slices Reference Point

**Use current system date?**

Tellius typically uses the maximum date in your dataset as the default reference point when calculating dynamic time slices (e.g., “last 7 days” or “previous month”).\
If enabled, Tellius will use the **current system date** instead.

{% hint style="info" %}
Enabling this may lead to unexpected results if your dataset is not updated daily—such as showing empty results for recent periods.
{% endhint %}

### Include Current Time

**Include current time grain (e.g., day) in last X time queries**

This setting controls whether queries for "last X time" (like last 7 days) should include the current day/hour/week, depending on the selected time grain.

* If enabled, today is included in calculations.
* If disabled, queries will exclude the in-progress current period.
