# Domain Objects

## Frequency

Frequency is the cadence at which orders associated with a given opt-in are placed. Frequency is a tuple consisting of "every" and "every period". "Every period" may be days, weeks, months, or years, represented as `1`, `2`, `3`, and `4` respectively. "Every" is a positive integer multiplier applied to the period. Together, "every" and "every period" are represented as a string separated by an underscore.

**Examples**

| Frequency | Description    |
| --------- | -------------- |
| `1_1`     | Every 1 day    |
| `2_1`     | Every 2 days   |
| `4_2`     | Every 4 weeks  |
| `4_3`     | Every 4 months |
