# Calendar

> Understand the CalBudget calendar, running balance, month signals, and low-balance planning.

The calendar is the center of CalBudget. It shows the money events that affect an account and the projected balance for each day.

## Calendar model

Each account has its own forecast. Transactions are placed on the date they affect the account. CalBudget applies them in date order and carries the balance forward.

## What appears on a day

* Day number
* Projected balance
* Income and expense transactions
* Recurring occurrences
* Cleared state
* Overflow count when a day has more transactions than fit

Clicking an overflow indicator should expand the day so the user can review all transactions on that date.

## Running balance

The running balance is the projected account balance after the day's transactions are applied.

| Signal           | Meaning                                        |
| ---------------- | ---------------------------------------------- |
| Starting balance | The current known balance for the account.     |
| Daily balance    | The projected balance after that date's items. |
| Lowest balance   | The lowest projected day in the visible range. |
| Projected finish | The expected balance at the end of the period. |

## Month signals

Month signals summarize whether the plan is safe.

* **Income used** compares planned outflow against income.
* **Cleared** shows how much of the month has posted or been confirmed.
* **Recurring load** shows how much predictable spending is already loaded.

If a percentage exceeds a safe threshold, it should be visually clear. Over-limit values should use a warning color.

## Calendar range

The top balance chart covers 12 months from the selected month. For example, selecting May should show May through the following May.

## Common actions

* Add a transaction to a selected date.
* Drag a transaction to another day.
* Select a transaction to edit it.
* Mark transactions cleared.
* Move recurring instances one time or as a series.
* Expand busy days.

## Best practices

* Use the calendar for future decisions, not just record keeping.
* Keep the next 30 to 90 days accurate.
* Review the lowest balance before adding optional spending.
* Update the balance when reality changes.
