Calculate the difference between two dates online — in days, hours, minutes and more.
Work out the time between two dates and times, expressed in milliseconds, seconds, minutes, hours, days and weeks. Leave the second date blank to measure up to now.
Enter both dates; the "days" field gives the exact fractional difference, so you can round as you need.
Anything JavaScript's Date parser accepts — ISO 8601 (2024-01-31) is the most reliable.
