Date Calculator - Meetei Numerals
Calculate days, weeks, months, and years between dates with Meetei numeral system support.
A free online date calculator for computing the time between two dates or adding and subtracting time from a given date. Count days, weeks, months, and years between any two dates, with correct handling of leap years, varying month lengths, and daylight saving time transitions. The calculator also counts business days excluding weekends — and lets you choose which days count as weekends to match your country (Saturday-Sunday, Friday-Saturday, or Thursday-Friday). Add or subtract a number of days from a date to find a future or past date. Useful for project planning, contract deadlines, pregnancy due dates, and visa duration calculations.
About This Numeral System
Meetei Mayek numerals (꯰ through ꯹) are the digits of the Meitei script, used for Meitei (also called Manipuri), a Tibeto-Burman language spoken primarily in the Indian state of Manipur. Meitei is spoken by roughly 1.8 million people. The Meitei script has ancient origins but was largely replaced by the Bengali script for centuries; it was revived in the 20th century and added to Unicode in 2009. This calculator displays results in Meetei Mayek numerals for users who read and write in Manipuri using the traditional script.
How This Calculator Works
Date Difference Calculation: Difference = Date2 − Date1 (in milliseconds, then converted)
The calculator converts both dates to milliseconds since the Unix epoch, subtracts them, and converts the result into days, weeks, months, and years. Leap years and varying month lengths are handled by the JavaScript Date object. Business-day calculations exclude weekends, with configurable weekend days for different countries.

Frequently Asked Questions
How many days are there between two dates?
Enter your start and end dates in the date calculator and it shows the exact number of days between them, plus the breakdown in weeks, months, and years. It also counts business days (excluding weekends) if you need working-day totals. For example, from January 1 to December 31, 2025 is 364 days, or 261 business days (Monday through Friday).
How do I use the date duration calculator?
Enter a start date and an end date. The calculator computes the total duration in days, weeks, months, and years. For example, from March 1 to September 15 is 198 days, or 28 weeks and 2 days, or approximately 6.5 months. The calculator also shows business days (excluding weekends) and lets you configure which days count as weekends for different countries.
How do I use the days between dates calculator?
Enter your two dates and the calculator shows the exact count of days between them. The calculation is exclusive of the end date by default — from January 1 to January 5 is 4 days. You can also count inclusively if needed. The result includes a breakdown in weeks, months, and years, plus a business-day count that excludes weekends.
Why does my date calculation differ by one day from what I expected?
The most common cause is a time zone mismatch. If you count days between January 15 and January 20, the answer depends on whether you mean inclusive counting (6 days including both endpoints) or exclusive counting (5 days between them). This calculator uses exclusive counting by default. Another cause: if your dates span a DST transition, the clock shifts by one hour, which can affect hour-level calculations even though day-level calculations are unaffected.
Does it account for leap years?
Yes. The calculator correctly handles leap years, varying month lengths, and daylight saving time transitions. Leap years add February 29 to the count, and the calculator automatically detects leap years using the Gregorian calendar rule (divisible by 4, except century years which must be divisible by 400).
How do I count business days excluding weekends in different countries?
The calculator lets you choose which days of the week count as weekends. Most countries use Saturday-Sunday, but several Middle Eastern countries use Friday-Saturday, and some use Thursday-Friday. Set the weekend days in the calculator settings to match your region before counting working days.
What can the date calculator compute?
The date calculator can find the number of days, weeks, months, and years between two dates. It can also add or subtract a number of days from a given date to find a future or past date, and count business days excluding weekends and holidays.
Why was the Meitei script replaced by Bengali script?
In the 18th century, the Kingdom of Manipur adopted Bengali script under the influence of Hinduism, specifically Vaishnavism. The traditional Meitei script (Meetei Mayek) fell out of official use for nearly two centuries. A revival movement began in the 20th century, and the script was added to Unicode in 2009. Today it is taught in Manipuri schools and used in cultural publications, though Bengali script remains common for everyday writing.
