Which date comes first?
Enter the certificates and surveys you hold, with their expiry dates. You get them sorted by nearest date, with days remaining, anniversary dates and a calendar file you can drop straight into Outlook. Everything is calculated in your browser; nothing is stored and nothing is sent.
Enter a name and an expiry date to see the overview.
What this tool does not do
It does not tell you which certificates your vessel must hold. That list depends on vessel type, trading area and flag state. The maritime regulatory basis is not loaded yet. Analysis therefore rests on the documents you upload and the particulars you register for the vessel. No convention or regulation reference is shown until the basis is in place.
The anniversary dates and windows are plain date arithmetic from the expiry date you enter. If the certificate follows a different scheme they do not apply. Always verify against the endorsement page on the certificate itself.
Several vessels, dozens of dates?
In Justera Maritime the dates sit with the vessel and stay there: alerts 90, 30 and 7 days ahead, and a date read from a document but not confirmed by a person is marked unconfirmed rather than shown as in order.
