Day Counting: An Exact Tally Between Two Dates
"How many days until the exam", "when does my visa run out", "how many working days to the deadline" — all are variants of the same calculation: the number of days between two dates. Counting by hand, the varying month lengths (28-31 days) and leap years (Feb 29) invite mistakes; this tool counts in full accordance with calendar rules and gives the result not just as total days but as weeks + days, working days (Monday–Friday) and weekend breakdown. The working-day count is the figure most needed for deliveries and official deadlines; public holidays differ by country, so they are not included.
The second mode answers the reverse question: "what date is 90 days from today?" By adding or subtracting days, weeks or months you see which date the result lands on and which weekday it is; practical for return windows, trial expirations, medication courses and contract periods. All calculation happens in your browser; the dates you pick are never sent anywhere.
