List US federal holidays for a year, with observed dates.

Observed dates matter more than actual ones for deadlines: a holiday on a Saturday closes offices the Friday before.

Count business days between two dates, skipping weekends and US federal holidays. Dates are ISO format (YYYY-MM-DD).

Add (or subtract, with a negative number) business days to a date, skipping weekends and US federal holidays.

Work backward from a funder deadline to the dates that actually matter.

A deadline is not a plan. This returns when to start drafting, when the internal review copy is due, and when the packet must be complete, using realistic lead times with weekends and federal holidays handled.

Build a grant budget with fringe and indirect calculated on the correct base.

indirect_base: 'mtdc' (Modified Total Direct Cost) or 'tdc' (Total Direct Cost).

MTDC is the common federal base and it EXCLUDES equipment and the portion of each subaward/contract above the first $25,000. Applying your rate to total direct costs instead is the single most common budget error, and it inflates the ask in a way reviewers notice.

Value volunteer time for match requirements or an annual report.

Defaults to the published national rate. Skilled volunteers doing professional work (legal, accounting, medical) should be valued at the rate for that work instead, which most funders accept if you document it.

Total donated goods and services. Each item needs 'description' and 'fair_market_value'; optional 'quantity' (default 1).
