Hello, I’m Junaid Ahmed — the founder, developer, and primary researcher behind datetime.pro.bd. I built this site out of a practical need and a cultural commitment: to provide accurate, transparent, and easy-to-use Bengali, Gregorian, and Hijri date tools for Bangladeshis at home and abroad. While working on calendars for my own projects and daily life, I repeatedly encountered a common problem — many online converters produced results that did not match official references. Dates for festivals, public holidays, and religious observances often differed from those published by Bangla Academy or by official government notices. That inconsistency directly affected planning for events, publishing schedules, religious observances, and software that depends on precise local dates. datetime.pro.bd is my answer to that problem.
A concrete use case that pushed this project forward: while preparing a public events calendar and coordinating festival dates for a community organization, I compared multiple popular converters and found discrepancies with the Bangla Academy calendar and government gazettes. Those small mismatches created real-world confusion—event invitations went out with the wrong day, developers implemented incorrect date logic in websites, and readers received conflicting information about important observances. To fix this, I designed datetime.pro.bd to prioritize alignment with official and authoritative sources and to make that alignment both visible and verifiable to users.
Technically, I approach each conversion and calendar calculation with rigor. I combine modern web development practices and tested date algorithms with regional calendar rules that matter for Bangladesh. That includes implementing Bangla calendar calculations, using appropriate Hijri calculation methods for regional observance, and testing against tabular and region-specific Islamic calendar references where relevant. Rather than trusting a single library, I cross-check outputs against official publications (Bangla Academy listings, government holiday notifications, and recognized Hijri references) and maintain a test-suite to flag discrepancies. When differences arise between algorithms and official sources, I investigate, document the root cause, and correct the logic or note the reason for the variance.
From an E-E-A-T perspective, datetime.pro.bd is built on experience (hands-on development and repeated real-world testing), expertise (practical knowledge of calendar systems and programming), authoritativeness (alignment with official sources and transparent methods), and trustworthiness (open contact channels and a commitment to continuous improvement). All tools and informational pages are developed or personally reviewed by me. Where interpretation is required—like local Hijri sighting conventions or region-specific Bangla rules—I clearly explain the method used and provide references so users can understand how results were derived.
This is an evolving project. I continuously update conversion logic, fix edge-case errors reported by users, and add features that help people use date data reliably—APIs for developers, printable calendars for publishers, holiday lists for planners, and quick converters for everyday users. I also encourage feedback and corrections: if you find a mismatch with an official notice or a cultural calendar, please tell me so I can investigate and correct it promptly.
If you rely on dates for planning, publishing, development, or religious observance and want a dependable reference that is built with local context and verified against authoritative sources, datetime.pro.bd was made for you.
