# Customizing the calendar view
The calendar view can be changed per your requirements. Navigate to **Settings -> Application Settings -> Time Configuration.**
Time configuration
1. Click on the dropdown under **First Day of Week** to change the first day to be displayed in the calendar view.
2. Switch on the toggle under **Time Slices Reference Point** to use your current system date as the reference point.
{% hint style="warning" %}
Tellius uses the **Max Data Date** as default. Switching to the current system date may cause errors if your data is not regularly updated. \
\
"**Max Data Date**" refers to the latest or most recent date present in the data.
{% endhint %}
3. Switch on the toggle under **Include current time** to include the current day as a part of specific time periods (e.g., *show me revenue from the last 7 days* should include today or not?) in search queries.
