Information and Data Accuracy

The algorithms and data sources used to provide information on this webpage and the calendar subscriptions provide accuacy within minutes. This is an intentional trade-off to limit processing time and CPU load on the hosting infrastructure.
For most civil applications, this should be good enough. Specifically, the algorithm used to calculate ΔT (delta-T) is a rough extrapolation and does not reflect earth's rotation accurately. However, this is reviewed periodically and adjusted if required.

Changes

This disclaimer may be updated at any time without notice. Changes will be posted on this page.
