Humanitarian Needs & Cost Planner
Estimate what a population needs per day, per week and per month — water, food, shelter, sanitation and household items — grounded in the Sphere Handbook minimum standards, for project proposals and strategy planning. Quantities are cited standards; costs are yours to enter, since local prices vary by country, market and time.
Based on the Sphere Handbook (Humanitarian Charter and Minimum Standards in Humanitarian Response, 2018 edition) and common inter-agency reference quantities. These are minimum planning figures for a general population — adjust for your specific context, demographic breakdown and the guidance of the relevant cluster before using in a submitted proposal.

Calendar converter FAQ
Can I convert Gregorian dates to Persian, Jalali, or Shamsi dates?
Yes. Select Persian / Jalali / Shamsi. Persian script and English appear together automatically.
Can I convert Gregorian dates to Hijri or Islamic dates?
Yes. Select Islamic / Hijri or Islamic Umm al-Qura. This supports Arabic-language reports, regional coordination and training schedules.
Why does calendar availability vary by browser?
The converter uses modern browser Intl and Unicode calendar data. Availability can vary in older browsers, so unsupported output fails closed instead of inventing a date.
Can I use these results in contracts or financial documents?
Use them for drafting and comparison. Verify legal, procurement, medical, engineering, financial and contract-critical results against the controlling source.
