About this tool
How many days until a deadline, since an event or between two dates? Pick the dates and get the total in days, in weeks and days, and as years, months and days, with how many of them fall on a weekend. Tick 'count the end day too' when both ends count, as with hotel nights or holidays. In the other mode, add or subtract any number of days from a date and see the resulting date and weekday - handy for deadlines of 30, 60 or 90 days. Runs in your browser.
