+## Understanding custom period budgets
+
+To get the most benefit from your custom period budget and more effectively manage your budgets, consider the following:
+
+  * **Set an appropriate budget time frame.** Choose a start and end date that aligns with your budgeting cycle. The end date must be within three years of the start date.
+
+  * **Understand your budget calculations.** Budget tracking uses the full date range, from start to end. For amount calculations, only the date (00:00 UTC) is used. The start date is included, but the end date is excluded from calculations.
+
+  * **Optimize your forecast alerts.** You can set forecasts up to 3 years in the future. Forecasting begins when the current date is within 12 months of the end date. Alert triggers are restricted to this 12-month time frame.
+
+  * **Maintain active monitoring.** Custom period budgets don't auto-renew and expire on the end date. Regularly review your budgets and extend end dates as needed to ensure continuous monitoring.
+
+  * **Consider your billing cycle.** Align your custom period budget with your billing cycle for more accurate tracking.
+
+  * **Use with other budget types.** Combine custom period budgets with monthly, quarterly, or annual budgets for comprehensive financial monitoring.
