Calculate analytics cookie expiry dates and TTL from duration settings — plan consent banners and privacy policies.
Expires within 90 days
= 90.00 days
What this tool does
Analytics and marketing cookies need documented lifetimes for GDPR consent banners and privacy policies.
Calculate exact expiry timestamps and remaining TTL from duration settings — no upload required.
How to use it
- 1
Enter cookie duration in days, hours, or a specific expiry date.
- 2
See the exact expiration timestamp and remaining TTL.
- 3
Copy results for privacy docs or analytics configuration.
Compliance context
Cookie policies must match actual tag behavior — a 90-day analytics cookie documented as 30 days creates compliance gaps.
Align TTL with your consent management platform settings and re-check after tag updates.
Tips
- List all third-party cookies in your privacy policy with accurate durations.
- Re-run calculations when switching analytics vendors.
