# Time Definition

Within FinOps Center, we currently support Annual Budgets that are aligned to Calendar years. 

Another key Time definition is Period. A Period represents the Work Week for Billing and is defined as below:

For Spend Cards, the First Period of each month is from the 1st day till Saturday 11:59. The Last Period of each month is Sunday 00:01 till the last day of the month.&#x20;

Spend Cards run every Monday for the previous Period. The final Cards run when FinOps Center recieves a CUR with the AWS Invoices that signifies the Spending is final.&#x20;

Within FinOps Center, the AWS spend as of - is approximately 1 hour after the Cost and Usage report has created a new file.  As FinOps Center leverages S3 Bucket Replication it can take time for all of the Cost and Usage data to Replicate so we wait to start the spending onboarding.&#x20;
