---------------------------------------------------------------------

## Overview

There are two types of dates in Fynapse important for the general configuration of the system:

* System Date - this is the actual date and time of the machine you are using to work with Fynapse; System Date does not differentiate between working and non-working days
* Business Date - this is the date and time configured for Fynapse processing; Business Date differentiates between working and non-working days based on the Business Calendar configured for the Subledger Node; Business Date is always a working day

By default, the Business Date is equal to the System Date, unless the System Date falls on a non-working date, then the Business Date is equal to the first next working day.

For example, if the System Date is January 1st, which is a non-working day, the Business Date is January 2nd, as illustrated by the timeline below:

You can enable Business Date override for testing purposes **on non-production environments** by hardcoding a specific date and time. For override, you can select a non-working day.
Please note that:

1. If Business date override is enabled, future dated Journals and Balances will not be visible on Journals and Balances screens.
2. Enabling Business Date override significantly affects the processing of the system:
   1. Future dated transactions, including scheduled transactions such as reversals, will be posted, but will not be visible on Journals and Balances screens.
   2. Past dated transactions that fall within a closed period and should not be posted will be posted if the override date forcibly opens the closed period.

For more details, refer to **How to Configure Business Date for Testing/Non-production Environments?**

## Where Do We Use Business Date?

Business Date is used to determine the statuses of periods in Fynapse, whether a period is open or closed.

Below is an example of the relation between System Date and Business Date and the period status, for a configuration where Business Day shift is set to -1.

</Frame>

Based on this information, Fynapse determines whether a Business Event can be posted to a given period.

Example:

This is an example of a configuration with 3 Grace Days defined. For this configuration, only working days are included in the period calculations.
