Date Calculator
How many days between two dates? What day is N days from now? Duration and date add/subtract in one page.
Count the days between two dates, or find out what date it'll be a number of days from now. Weeks, months and years are broken down instantly as you pick.
Off: the gap between the dates. On: the start day counts as day 1 (e.g. "how many days we've been together").
The OgleOgle Date Calculator works out the span between two dates and the date that falls a given number of days before or after a reference date — all on one page. In duration mode, enter a start and end date to see the total number of days, the span in weeks, the breakdown in years, months and days, and the weekday of each date; an 'include start date' toggle makes it perfect for 'how many days since', 100-day, and D+ counts. In add/subtract mode, add or subtract days, weeks, months or years from any date and instantly get the resulting date and its weekday, with month-end overflow handled automatically. Pair it with the age and D-day calculators to answer almost any date question in seconds.
