Day count calculator

That's the basic function of our date to date calculator. It's helpful, no matter if you want to know how many days have passed since you got engaged, or how many days off you need for that dream tour around the whole world.

There might be one problem though - one answered question can open the door to many other queries...

Or even...

Year to date calculator

Our date counter can provide you with the result shown in years. It will also convert the period you calculated into dog years. 🐕

🙋 Did you know?
..that different religions count years differently?
In Western tradition, we are currently in the year 2020. But, according to Hebrew calendar, it's year 5780, while the Islamic tradition tells us it's year 1441!

Yes, we love presenting you with all the curiosities we can find.

Are our dates real? In October 1582, European countries began to change their calendar from the Julian one to the Gregorian one. This modification was necessary, as the Julian calendar did not match the astronomical properties of your planet.

The process of change was long and complicated - dates had to change by 10 days. Right now, the difference between these two systems is 13 days. Can you imagine living the same day a few times in a row, or being robbed of 10 days of your life? This calendar change is the reason why it's rather difficult to calculate the dates between European events in the XVI century, not everyone changed at once. For some time, to avoid confusion, the dates were written in both formats - and to their horror they had no date day to day calculators back then 😉.

The United Kingdom was one of the countries that postponed accepting the "new order" of time: died 10 days after . However, the official dates of their deaths are still identical - the 23rd of April of 1616!

Additional complications arise from the fact that the UK's new year use to begin on the 25th of March - the day of Annunciation. It was in opposition to the majority of Europe that followed the usual trend of the new year being celebrated on the 1st of January.

(Just letting you know, you can still compute the Julian calendar date of any event with our day difference calculator - just change the difference of days to 13. 😉)
