How to use the Elapsed Time Calculator:
Set each date to a time in the past or the future, or NOW.
(Click on NOW and change to "Choose a date" if you want to set both dates.)
Click and type or use the arrows to change the year. Use the drop-down menus or arrows to change months, days, hours, minutes, or seconds.
(Future dates have a pale green background; past dates have a darker green background.)
Ideas ~ Looking into the Future:
What is the countdown from now to the last day of school?
What is the countdown to your next birthday?
If you are alive at the turn of the next century on January 1, 2100,
how old will you be?
How many months, weeks, days, minutes, and seconds are there in 1,000 years?
Ideas ~ Looking into the Past:
How much older is (a parent) than you?
How long has it been since the birth of your country?
How long has it been since the invention of ________ ?
(Look up the year it was invented and plug it in here.)
How long ago did man first walk on the moon?
The Math Cats Elapsed Time Calculator will not accept dates earlier than 1582.
It is very hard to figure out an exact elapsed time for dates earlier than 1582,
when a different calendar system was in use. Most of the world now uses the
Gregorian calendar
, and that is the calendar used here.
