UCC / CommercialLegal glossary term
Quick answer
INTERVAL usually means a set period between two contractual events. In contracts, it matters because missing it can trigger breach or loss of rights. Before signing, check the exact dates and any “of essence” language.
Definitions
What is interval?
Legal Definition
An interval sets the period between two defined events in a contract or statute. It creates a deadline that triggers performance or a breach if the time limit is missed. The most critical qualifier is whether the interval is of essence, which can make delay a material breach.
Plain-English Translation
Think of a hall pass that lets you be in the cafeteria for exactly ten minutes; if you stay longer, you’re in trouble.
Contract relevance
Why interval matters in contracts

Party impact
How interval affects each party
| Party | What this party should check |

| Lender | Needs to confirm reporting deadlines to protect loan covenants |
| Tenant | Must know rent due date to avoid late fees |
Comparison
interval vs similar terms
| Related term | Plain meaning | Main difference from interval |
|---|---|---|
| Grace period | Extra time after the interval expires | Unlike interval, it offers leniency |
| Time of the essence | Clause making the interval mandatory | Makes any delay a material breach |
| Force majeure | Event that suspends obligations | Can excuse performance even within a set interval |
Missing or vague
If interval is missing or vague
If the interval is left undefined, parties may argue over when performance was due, leading to costly litigation.
A borrower might claim a later reporting date, while the lender insists on an earlier one.
Without clear timing, the risk of default or loss of rights increases for the party relying on the deadline.
