How it works
- How do I work out the date a number of days from today?
- Enter the number of days and choose “after the start date”. The calculator adds the days to today and shows the exact date and weekday.
- What happens when I add a month to 31 January?
- The result clamps to the last day of the target month, so 31 January plus one month is 28 February (29 February in a leap year).
- Do the counts include today?
- No. Day one is tomorrow, so “30 days from today” lands 30 days after today's date rather than 29.
