A calendar service to make sense of events


Our online service can help you make sense of old records and determine actual dates of events. We have started with Danish church books and the Danish calendar, but our ambition is to extent and be useful with other countries' records.


Determine dates from old records

In old Danish church books dates are sometimes noted relative to church days. Our online calendar service, helps you determine the actual dates from these descriptions. 


Calculate birth and death days

In some cases you may only be able to find the date of death and an age, and our online service can then help you determine the date of birth.


Calendar switches

Our online service keeps track of national switches between calendars. As a start it just keeps track of the Danish switch from the Julian calendar to the Gregorian calendar in 1700. But we intent to expand to other countries.
