FAQ
Frequently asked questions
Here are clear answers about privacy, date rules, and how these tools should be used.
A quick reminder
Date tools are suitable for everyday planning. They should not replace legal, financial, medical, or official determinations of dates and deadlines.
Does DateCraft save the dates I enter?
No. Calculations happen in your browser. This site has no login system and does not send your date inputs to a server.
Does the date difference include the start date?
By default, the tool measures the interval between the dates without counting the start date twice. Selecting the inclusive option adds one day.
Does the business day calculator include public holidays?
Only Saturdays and Sundays are excluded by default. Add public holidays manually as extra excluded dates.
Does the time zone converter handle daylight saving time?
The converter uses the time-zone rules available in your browser when possible. Confirm important meetings with an official calendar.
Can I use DateCraft for a commercial project?
Yes, for general organization and planning. Read the Terms of Use for limitations and responsibilities.
