Project forward or backward from any date: deadlines 90 days out, warranty ends, notice periods, follow-up dates — with the weekday named.
How it works
- Set your starting date (or leave blank to use today).
- Enter the numerical amount to add (use a negative number to subtract).
- Select your unit (days, weeks, months, years) and see the exact resulting date.
Frequently asked questions
What is 90 days from today?
Leave the start date blank — it defaults to today — and the result updates instantly.
Why did Jan 31 + 1 month give Feb 28?
February has no 31st; calendar math clamps to the month's last day, the standard convention.
Can I subtract?
Yes — enter a negative amount to go backward.
Does it skip holidays?
No — it adds calendar days. For business-day addition that skips weekends, use the Add Business Days calculator.
