Parsing and Server Use

Parse and format dates on the server with Tarikh, including Bangla and Hijri calendar conversion.

Start Here

Tarikh works directly on the server for formatting, parsing, and calendar conversion.

Quick Rule

If you are rendering data in loaders, server components, or scripts, this is the page to check.

import { format, parseDate, toBanglaCalendar, toHijriCalendar } from "@coreify/tarikh";

parseDate("৩১ মার্চ ২০২৬");
parseDate("17 Chaitra 1432", { calendar: "bangla" });
parseDate("2026-03-31T15:30:00Z");

format("2026-03-31", { mode: "standard" });
format("2026-03-31", { mode: "bangla", locale: "bn-BD" });
format("2026-03-31", { mode: "hijri", timeZone: "UTC" });

toBanglaCalendar("2026-03-31", { locale: "bn-BD" });
toHijriCalendar("2026-03-31", { timeZone: "UTC" });

Input Shapes

Input	Result
`Date`	Normalized through `toDate()`
Timestamp	Accepted when finite and in range
Gregorian strings	ISO dates, common date formats, and timestamps
Bangla strings	Parsed when `calendar: "bangla"` is provided

Supported Gregorian Formats

YYYY-MM-DD
YYYY/MM/DD
YYYY.MM.DD
YYYY-M-D, YYYY/M/D, YYYY.M.D
YYYY-MM-DDTHH:mm[:ss[.fraction]][Z|±HH:mm]
DD Month YYYY
Month DD, YYYY
DD-Month-YYYY
Bangla calendar strings like 17 Chaitra 1432
Common Bangla month aliases like Boishakh, Poush, Falgun, and Asharh

Timezone Control

Setting	Effect
Default Hijri timezone	`Asia/Dhaka`
`timeZone: "UTC"`	Uses the canonical UTC Hijri result
`HIJRI_TIME_ZONES`	Runtime list and TypeScript union for supported zones

Notes

format() is the highest-level entry point for server rendering
parseDate() returns a native Date
toDate() accepts the same Gregorian strings plus Date objects and timestamps
