About this tool
Find how many calendar days have passed since a past date.
Select a past date. NUMTX counts calendar-day boundaries rather than elapsed 24-hour blocks.
Method
Days since = today − selected calendar date.
Example
Use it to measure time since a milestone, purchase, event or start date.
Accuracy
NUMTX uses standards-based browser date and time functions. Device clock settings, time-zone data and regional daylight-saving rules can affect displayed time. For legal, travel or contractual deadlines, confirm the relevant official time zone and rules.
