Calculate days until date
Calculate days remaining until a target date from an explicit reference date.
Input & settings
How to use this tool
Enter your current local calendar date and the target date. Past targets return a negative number.
Limits and behavior
Uses the Gregorian calendar for years 1900–2100. Dates must be exact YYYY-MM-DD values. Calendar days are counted at UTC midnight, independent of daylight saving. The reference date is explicit, so results never silently depend on this device’s clock or time zone. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.
Find how many days until a future date
Compare a target calendar date to a chosen reference date to calculate days remaining or elapsed.
Does the result update automatically every second?
No. This calculates from the reference date provided; use a new date to recalculate.
