Example data table

Agreement	Basis	Base Date	Term	Tolling Days	Notice Days	Calculated Expiry
Vendor NDA	First disclosure	2024-02-15	3 years	0	30	2027-02-15

Formula used

1. Base date selection
Base Date = selected trigger date from the contract.

2. Standard confidentiality expiry
Expiry Date = Base Date + Years + Months + Days + Tolling Days

3. Reminder or notice date
Notice Date = Expiry Date − Notice Period Days

4. Days remaining
Days Remaining = Expiry Date − Reference Date

5. Term consumed percentage
Percent Consumed = (Elapsed Days ÷ Total Term Days) × 100

Interpretation note
The calculator models timing logic only. It does not replace legal drafting review, statutory analysis, or jurisdiction-specific enforceability assessment.

FAQs

1. What does this calculator measure?

It measures how long confidentiality obligations continue after a selected contract trigger. It also estimates reminder dates, expiry dates, elapsed time, remaining days, and separate trade secret timing when entered.

2. Which date should I use as the base date?

Use the date defined by the agreement. Some clauses run from the effective date, some from each disclosure, and others from termination. Match the contract language before relying on the result.

3. Can this calculator handle trade secrets?

Yes. You can mark trade secret obligations as indefinite while legally protected, or calculate a separate trade secret end date using a distinct term structure.

4. What are tolling days?

Tolling days are extra days added to the confidentiality term. Teams may use them when a contract pauses deadlines or extends obligations after a breach, dispute, or suspension event.

5. Does it replace legal advice?

No. It is a drafting and review aid. It calculates dates and timing assumptions, but a lawyer should confirm enforceability, survival wording, and jurisdiction-specific rules.

6. Why is there a notice reminder date?

The notice reminder date helps legal, procurement, or compliance teams review obligations before expiry. It can support extension decisions, document cleanup, or declassification workflows.

7. Can I export the results?

Yes. The page includes CSV export for structured data and PDF export for a shareable summary. These options appear after the calculation is completed.

8. What if my contract uses multiple disclosure dates?

This version calculates one base trigger at a time. For rolling disclosures, many teams calculate each disclosure separately or adapt the code to process multiple disclosure records.
