Unlike a static custom date range, the dates themselves shift forward as time passes, so you can set it up once in a custom dashboard and it stays current. ### Where You'll Find It Custom Dynamic appears as a drop-down option in three pickers inside the date range filter modal: 1. **Primary Range** 2. **Compare Ranges** (Compare, Compare #2, Compare #3) 3. **As Of** (Primary and every Compare range slot) Setting Up a Primary Range 1. Open the date range filter and select **Custom Dynamic** from the Primary Range dropdown. 2. Choose **Next** or **Last**. 3. Enter a **whole number**. *Numbers must be positive whole numbers (no decimals, zero, or negatives).* 4. Choose a time unit: **Days, Weeks, Months,** or **Years**. *Each time unit has a maximum: 999 Days, 150 Weeks, 50 Months, 5 Years.* 5. Click on Apply ![Screenshot 2026-08-24 at 1.04.57 PM](https://support.keydata.co/hs-fs/hubfs/Screenshot%202026-08-24%20at%201.04.57%20PM.png?width=670&height=362&name=Screenshot%202026-08-24%20at%201.04.57%20PM.png) The resolved date range appears live below the controls and updates as you make your selections. This field is read-only while the Custom Dynamic dropdown is selected, since the dates are calculated automatically rather than entered by hand. ### Setting Up a Compare Range Compare Ranges work the same way as Primary, with one addition: when your unit is Months or Years, a **same-day-of-week** checkbox appears. This keeps weekday alignment consistent with your Primary range for cleaner period-over-period comparisons. Day and Week time units already preserve weekday alignment automatically, so the checkbox only shows up when it's needed. ### Setting Up an As Of option As Of gets two new Custom Dynamic options: - **Custom Dynamic**: standard as-of tracking - **Custom Dynamic w/ Canceled**: same as above, but KPI calculations include reservations that were eventually cancelled after the As Of date. Both As Of Custom Dynamic options use the same number + time unit controls as Primary and Compare. ![Screenshot 2026-08-24 at 1.07.51 PM](https://support.keydata.co/hs-fs/hubfs/Screenshot%202026-08-24%20at%201.07.51%20PM.png?width=670&height=364&name=Screenshot%202026-08-24%20at%201.07.51%20PM.png) ### How It Displays in a Section Once configured, your filter and legend will show the resolved dates alongside the as-of date, for example: > Custom Dynamic 8/1/2026 to 3/31/2027, as of 8/24/2026 > > ![Screenshot 2026-08-24 at 1.09.43 PM](https://support.keydata.co/hs-fs/hubfs/Screenshot%202026-08-24%20at%201.09.43%20PM.png?width=670&height=51&name=Screenshot%202026-08-24%20at%201.09.43%20PM.png) Displayed dates update automatically each time you load the saved report or custom dashboard. ### Custom Dynamic vs. Custom Static The original "Custom" date range option is still available, but it is now labeled **Custom Static** to distinguish it. Custom Static still locks to the exact start/end dates that you've manually picked in the calendars and never changes these dates. ![Screenshot 2026-08-24 at 1.14.14 PM](https://support.keydata.co/hs-fs/hubfs/Screenshot%202026-08-24%20at%201.14.14%20PM.png?width=670&height=364&name=Screenshot%202026-08-24%20at%201.14.14%20PM.png) - Use Custom **Dynamic** when you want a range that stays current relative to today. - Use Custom **Static** when you need a fixed, unchanging date range window (ie. Spring Break dates in March-April, Ski season dates in Nov-March, etc). ### FAQs **Does my Custom Dynamic range update while I'm looking at the report?** No. It recalculates each time the section loads, not live in the middle of a session. **Can I save a Custom Dynamic range to a custom dashboard or saved report?** Yes, it saves and behaves the same way saved dates do today. **What happened to the old Minus One/Two/Three Years presets?** Those are still available as fixed presets in the Date Range drop downs. - [ProData & Property Managers](https://support.keydata.co/en/knowledge/prodata-property-managers?hsLang=en#main-content) - [NEW!
