Terms of use

Use Glassyear freely, and double-check anything that really matters.

Information only

Holiday dates are provided for general information. They can change by government decision, and estimated lunar dates can shift. Do not rely on Glassyear alone for legal, payroll, travel, or financial deadlines.

Widgets and API

You may embed our widgets and use our API on any lawful website or app, free of charge, with a visible link to Glassyear where practical. Do not overload the service; cache responses. We may limit abusive traffic.

The service is provided “as is”, without warranties of any kind. To the extent permitted by law, Mikado Lab Systems is not liable for losses arising from the use of the site.
